Detecting atmospheres around planets with a radius below 1.6 R$_{\oplus}$, commonly referred to as rocky planets (Rogers_2015, Rogers_2021), has proven to be challenging. However, rocky planets orbiting M-dwarfs are ideal candidates due to their favorable planet-to-star radius ratio. Here, we present one transit observation of the Super-Earth L98-59d (1.58 R$_{\oplus}$, 2.31 M$_{\oplus}$), at the limit of rocky/gas-rich, using the JWST NIRSpec G395H mode covering the 2.8 to 5.1 microns wavelength range. The extracted transit spectrum from a single transit observation deviates from a flat line by 2.6 to 5.6$\sigma$, depending on the data reduction and retrieval setup. The hints of an atmospheric detection are driven by a large absorption feature between 3.3 to 4.8 microns. A stellar contamination retrieval analysis rejected the source of this feature as being due to stellar inhomogeneities, making the best fit an atmospheric model including sulfur-bearing species, suggesting that the atmosphere of L98-59d may not be at equilibrium. This result will need to be confirmed by the analysis of the second NIRSpec G395H visit in addition to the NIRISS SOSS transit observation., Comment: Accepted for publication in the Astrophysical Journal Letters (ApJL), August 25, 2024

Astrophysics - Earth and Planetary Astrophysics - Abstract
L 98-59 d is a Super-Earth planet orbiting an M-type star. We performed retrievals on the transmission spectrum of L 98-59 d obtained using NIRSpec G395H during a single transit, from JWST Cycle 1 GTO 1224. The wavelength range of this spectrum allows us to detect the presence of several atmospheric species. We found that the spectrum is consistent with a high mean molecular weight atmosphere. The atmospheric spectrum indicates the possible presence of the sulfur-bearing species H$_2$S and SO$_2$, which could hint at active volcanism on this planet if verified by future observations. We also tested for signs of stellar contamination in the spectrum, and found signs of unocculted faculae on the star. The tentative signs of an atmosphere on L 98-59 d presented in this work from just one transit bodes well for possible molecular detections in the future, particularly as it is one of the best targets among small exoplanets for atmospheric characterization using JWST., Comment: Accepted for publication to ApJL

Astrophysics - Earth and Planetary Astrophysics - Abstract
Transmission spectroscopy is one of the most successful methods of learning about exoplanet atmospheres. The process of retrievals using transmission spectroscopy consists of creating numerous forward models and comparing them to observations to solve the inverse problem of constraining the atmospheric properties of exoplanets. We explore the impact of one simplifying assumption commonly employed by forward models of transiting exoplanets: namely that the planet can be treated as an isolated, non-rotating spherical body. The centrifugal acceleration due to a planet's rotation opposes the gravitational pull on a planet's atmosphere and increases its scale height. Conventional forward models used for retrievals generally do not include this effect. We find that atmospheric retrievals produce significantly different results for close-in planets with low gravity when this assumption is removed, e.g., differences between true and retrieved values of gas abundances greater than 1$\sigma$ for a simulated planet analogous to WASP-19 b. We recommend that the correction to the atmospheric scale height due to this effect be taken into account for the analysis of high precision transmission spectra of exoplanets in the future, most immediately JWST Cycle 1 targets WASP-19 b and WASP-121 b., Comment: 5 pages, 4 figures, accepted for publication in MNRAS Letters

JWST Transiting Exoplanet Community Early Release Science Team ,General Science & Technology - Abstract
Carbon dioxide (CO2) is a key chemical species that is found in a wide range of planetary atmospheres. In the context of exoplanets, CO2 is an indicator of the metal enrichment (that is, elements heavier than helium, also called 'metallicity')1-3, and thus the formation processes of the primary atmospheres of hot gas giants4-6. It is also one of the most promising species to detect in the secondary atmospheres of terrestrial exoplanets7-9. Previous photometric measurements of transiting planets with the Spitzer Space Telescope have given hints of the presence of CO2, but have not yielded definitive detections owing to the lack of unambiguous spectroscopic identification10-12. Here we present the detection of CO2 in the atmosphere of the gas giant exoplanet WASP-39b from transmission spectroscopy observations obtained with JWST as part of the Early Release Science programme13,14. The data used in this study span 3.0-5.5 micrometres in wavelength and show a prominent CO2 absorption feature at 4.3 micrometres (26-sigma significance). The overall spectrum is well matched by one-dimensional, ten-times solar metallicity models that assume radiative-convective-thermochemical equilibrium and have moderate cloud opacity. These models predict that the atmosphere should have water, carbon monoxide and hydrogen sulfide in addition to CO2, but little methane. Furthermore, we also tentatively detect a small absorption feature near 4.0 micrometres that is not reproduced by these models.

Astrophysics - Earth and Planetary Astrophysics ,Physics - Space Physics - Abstract
Transit searches have uncovered Earth-size planets orbiting so close to their host star that their surface should be molten, so-called lava planets. We present idealized simulations of the atmosphere of lava planet K2-141b and calculate the return flow of material via circulation in the magma ocean. We then compare how pure Na, SiO, or SiO$_2$ atmospheres would impact future observations. The more volatile Na atmosphere is thickest followed by SiO and SiO$_2$, as expected. Despite its low vapour pressure, we find that a SiO$_2$ atmosphere is easier to observe via transit spectroscopy due to its greater scale height near the day-night terminator and the planetary radial velocity and acceleration are very high, facilitating high dispersion spectroscopy. The special geometry that arises from very small orbits allows for a wide range of limb observations for K2-141b. After determining the magma ocean depth, we infer that the ocean circulation required for SiO steady-state flow is only $10^{-4}$ m/s while the equivalent return flow for Na is several orders of magnitude greater. This suggests that a steady-state Na atmosphere cannot be sustained and that the surface will evolve over time., Comment: 8 pages, 7 figures

This paper engages with the entwined questions of science and ideology through a symptomatic reading of Kazuo Ishiguro’s
Never Let Me Go (2005), studying how power, racism, and capital intervene into the genetic enterprise of tampering with the limitations of the human and produce a supplicant race of clones for organ harvest and extraction. I commence by drawing on Donna Haraway’s concept of gene fetishism and Evelyn Fox Keller’s notion of gene talk to trace how an elision of the ideological frameworks of race and capital subtending genomics in Ishiguro’s dystopian world instrumentalizes the creation of the clones as racialized products. I bring into dialogue the clones’ obsessive quest for familial origins with Deborah Bolnick’s exploration of the reification of race as biology through ancestry tests to analyze how technology can be used to create and legitimize racism. Deploying Kaushik Sundar Rajan’s theorization of biocapital and James Doucet-Battle’s analysis of the intersections of race, capitalism, and time, I study how the clones are discursively defined as fungible commodities in service to a futurity from which they are precluded. I conclude by positing the call for “slow science” as a potential strategy against the accelerationism and market-ready speculations that dictate biotechnical enterprises today.

The poems of Sylvia Path are characterized by an ingenious deployment of time genre of time elegy towards an evocation of self negation in a hostile patriarchal post Holocaust world. Defining the elegy as an aestlmetic reflection on deatli, time paper endeavours to trace Plath's journey towards self annihilation using time textual codes embedded in her nmost celebrated poems. Time paper thus seeks to illunmine Imow, for Path, boundaries of the real and the literary are blurred and porous, with personal anxieties bleedinginto textual spaces. Time inability of tlmese texts, contaminated as tlmey are by time commercial realities of a late capitalist system, to purge or at l.east contain tlmese anxieties is then revealed. Time paper concludes witlm a brief analysis of her last poem 'Edge' culminating in her suicide where time text/context binary ultimately collapses in the undifferentiated amalgamation of art and life.
