Abstract

The intensity spectra recovered from the spectroscopic photographic plates were compared with the CCD spectra, and we found the difference between the two was 2.5%.The measurements were taken using a commercial flatbed scanner instead of a microdensitometer. The results indicate that the following two statements are inaccurate: (1) Correct measurement of spectroscopic plates requires a microdensitometer, and a commercial flatbed scanner is insufficient; (2) The spectrophotometric accuracy of spectroscopic plate is approximately 10% accurate. These results will encourage the creation and publication of a digital archive of spectroscopic plates. This paper presents the measurement of spectroscopic plates, the method of recovering intensity spectra from photographic density spectra, the results of comparison with CCD spectra, and discusses the causes of the high accuracy spectra obtained with a commercial flatbed scanner.

Abstract

The linear polarization degree (referred to the scattering plane, P_r) as a function of the solar phase angle, {\alpha}, of solar system objects is a good diagnostic to understand the scattering properties of their surface materials. We report Pr of Phaethon over a wide range of {\alpha} from 19.1 deg to 114.3 deg in order to better understanding properties of its surface materials. The derived phase-polarization curve shows that the maximum of P_r, P_max, is >42.4% at {\alpha} >114.3 deg, a value significantly larger than those of the moderate albedo asteroids (P_max ~9%). The phase-polarization curve classifies Phaethon as B-type in the polarimetric taxonomy, being compatible with the spectral property. We compute the geometric albedo, p_v, of 0.14 +/- 0.04 independently by using an empirical slope-albedo relation, and the derived p_v is consistent with previous results determined from mid-infrared spectra and thermophysical modeling. We could not find a fit to the period in our polarimetric data in the range from 0 up to 7.208 hr (e.g., less than twice the rotational period) and found significant differences between our P_r during the 2017 approach to the Earth and that of the 2016. These results imply that Phaethon has a region with different properties for light scattering near its orbital pole., Comment: 30 pages, 3 figures, 3 tables (includes long data table)

Abstract

We present a measurement of H2O ice crystallinity on the surface of trans-neptunian objects (TNOs) with near-infrared narrow-band imaging. The newly developed photometric technique allows us to efficiently determine the strength of an 1.65-um absorption feature in crystalline H2O ice. Our data for three large objects, Haumea, Quaoar, and Orcus, which are known to contain crystalline H2O ice on the surfaces, show a reasonable result with high fractions of the crystalline phase. It can also be pointed out that if the H2O-ice grain size is larger than ~20 um, the crystallinities of these objects are obviously below 1.0, which suggest the presence of the amorphous phase. Especially, Orcus exhibits a high abundance of amorphous H2O ice compared to Haumea and Quaoar, possibly indicating a correlation between bulk density of the bodies and surface crystallization degree. We also found the presence of crystalline H2O ice on Typhon and 2008 AP129, both of which are smaller than the minimum size limit for inducing cryovolcanism as well as a transition from amorphous to crystalline through the thermal evolution due to the decay of long-lived isotopes., Comment: 31 pages, 7 figures, 6 tables, accepted for publication in ApJ

Abstract

We report short-time variations in the plasma tail of C/2013 R1(Lovejoy). A series of short (two to three minutes) exposure images with the 8.2-m Subaru telescope shows faint details of filaments and their motions over 24 minutes observing duration. We identified rapid movements of two knots in the plasma tail near the nucleus (~ 3 x 10^5 km). Their speeds are 20 and 25 km/s along the tail and 3.8 and 2.2 km/s across it, respectively. These measurements set a constraint on an acceleration model of plasma tail and knots as they set the initial speed just after their formation. We also found a rapid narrowing of the tail. After correcting the motion along the tail, the narrowing speed is estimated to be ~ 8 km/s. These rapid motions suggest the need for high time-resolution studies of comet plasma tails with a large telescope., Comment: 13 pages, 7 figures; AJ accepted

Abstract

Comet C/2007 N3 (Lulin) was observed with the Japanese infrared satellite AKARI in the near-infrared at a post-perihelion heliocentric distance of 1.7 AU. Observations were performed with the spectroscopic (2.5--5.0 micron) and imaging (2.4, 3.2, and 4.1 micron) modes on 2009 March 30 and 31 UT, respectively. AKARI images of the comet exhibit a sunward crescent-like shape coma and a dust tail extended toward the anti-solar direction. The 4.1 micron image (CO/CO2 and dust grains) shows a distribution different from the 2.4 and 3.2 micron images (H2O and dust grains). The observed spectrum shows distinct bands at 2.66 and 4.26 micron, attributed to H2O and CO2, respectively. This is the fifth comet in which CO2 has been directly detected in the near-infrared spectrum. In addition, CO at 4.67 micron and a broad 3.2--3.6 micron emission band from C-H bearing molecules were detected in the AKARI spectrum. The relative abundance ratios CO2/H2O and CO/H2O derived from the molecular production rates are \sim 4%--5% and < 2%, respectively. Comet Lulin belongs to the group that has relatively low abundances of CO and CO2 among the comets observed ever., Comment: 14 pages, 2 tables, 2 figures, accepted for publication in The Astrophysical Journal Letters

12. SPICA Spectroscopy of Cometary Refractory and Icy Dust Grains

Author

Abstract

SPICA Science Conference from Exoplanets to Distant Galaxies: SPICA's New Window on the Cool Universe (June 18-21, 2013. Ito Hall, the University of Tokyo), Bunkyou-ku, Tokyo, Japan, We propose mid/far-infrared spectroscopy of comets to study (1) precise astromineralogy of cometary refractory dust and, (2) environment of H2O ice formation (temperature and gas density) in the early solar nebula. The mid/far-infrared spectroscopy is a powerful diagnostic tool to investigate the size, shape, and chemical composition of cometary dust, so that it will enable us to reveal the process of refractory grain growth and radial transportation of dust grains in the early solar nebula. However, it is not easy to disentangle constituent minerals clearly only with the 10 μm-band of ground-based observations. The crystalline silicate bands at 33, 49, and 69 μm are a clue to investigate the dust size and chemical composition. Whether cometary H2O icy dust grain is amorphous or crystalline reflects its formation environment (temperature and gas density). The H2O ice bands are at 6, 12, 44 and 65 μm. Since the reason why crystalline H2O icy grains were detected in a few comets is still unclear, statistical study on the abundance of the cometary crystalline H2O ice dust is important to reveal the history of formation and evolution of the comets., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1730027085, レポート番号: JAXA-SP-17-010E

Abstract

International audience; The Space Infrared telescope for Cosmology and Astrophysics (SPICA) is planned to be the next space astronomy mission observing in the infrared. The mission is planned to be launched in 2017 and will feature a 3.5 m telescope cooled to 30 microns wavelength). We describe the scientific advances that will be made possible by this large increase in sensitivity and give details of the mission, spacecraft and focal plane conceptual design.

39. Spin Temperature of Ammonia Determined from NH2 in Comet C/2001 A2 (LINEAR)

Abstract

The ortho-to-para ratio (OPR) of a cometary molecule is one of primordial character in comets. The OPR which is characterized by a spin temperature, is thought to reflect the formation conditions of the molecule. In this paper we show the high-dispersion spectrum of cometary NH2 in Comet C/2001 A2 (LINEAR), from which the OPR of NH2 is determined based on the fluorescence excitation model. Since the NH2 is a photodissociation product of cometary ammonia, we applied the permutation group theory to the whole reaction system (i.e. the photodissociation reaction of ammonia to NH2 and H) in order to derive the OPR of ammonia from that of NH2. The derived OPR of ammonia is 1.12 ± 0.03 in Comet C/2001 A2 (LINEAR). This value corresponds to a spin temperature of 30+3-2 K. If this reflects the temperature where the comet formed in the protosolar nebula, our result indicates that thiscomet was formed in the region of the giant planets between Jupiter and Neptune.
