Observation of the Apoapsis of S62 in 2019 with NIRC2 and SINFONI

Given the increased attention toward the detection of faint stars in the Galactic center, we would like to address the detectability of S62 in its apoapsis with the Spectrograph for INtegral Field Observations in the Near Infrared at the Very Large Telescope (SINFONI; VLT) and the Near-Infrared Camera 2 (NIRC2; KECK) in this work. Because of the nearby stars and the chance of confusion, we are using Lucy-Richardson deconvolved images to detect S62 on its Keplerian orbit around Sgr A* with a period of less than 10 yr. We use the same data set as for S62 to trace additionally the S-cluster star S29 at the expected position based on the orbital elements presented in this work. To verify the results of the filtering technique, we are analyzing K-band continuum data of the same epoch independently observed with NIRC2/KECK. Based on the well-derived orbit of S62, we find the star in projection at the expected position in 2019.4 and 2019.5. By analyzing the SINFONI data of 2019.5, we confirm the 16.1 +/- 0.2 mag for S62 that was formerly derived with NAOS-CONICA (NACO; VLT). We base our NACO imaging analysis on the robust data set that was previously used to investigate the Schwarzschild precision of S2. We also present a critical discussion of the elsewhere proposed linear trajectory of S62 and its disputed identification with a 19 mag star found with GRAVITY mounted at the VLT Interferometer.
