X-ray spectral and temporal evolution of atoll source 4U 1820-30 with AstroSat: detection of high frequency quasi-periodic oscillation
Subhasish Das, Vivek Kumar Agrawal, Parijat Thakur +4
AstroSat/LAXPC and SXT observed the persistent neutron star low-mass X-ray binary 4U 1820-30 between 2016 and 2022. During these observations, the hardness-intensity diagram (HID)…
Transit Timing Variations of the Sub-Saturn Exoplanet HAT-P-12b
Kaviya Parthasarathy, Hsin-Min Liu, Ing-Guey Jiang +12
We present Transit Timing Variations (TTVs) of HAT-P-12b, a low-density sub-Saturn mass planet orbiting a metal-poor K4 dwarf star. Using 14 years of observational data (2009-2022)…
Revisiting the Transit Timing Variations in the TrES-3 and Qatar-1 systems with TESS data
Vineet Kumar Mannaday, Parijat Thakur, John Southworth +12
We present and analyze 58 transit light curves of TrES-3b and 98 transit light curves of Qatar-1b observed by Transiting Exoplanet Survey Satellite (TESS), plus two transit light c…
The Transit Timing and Atmosphere of Hot Jupiter HAT-P-37b
Napaporn A-thano, Ing-Guey Jiang, Supachai Awiphan +13
The transit timing variation (TTV) and transmission spectroscopy analyses of the planet HAT-P-37b, which is a hot Jupiter orbiting an G-type star, were performed. Nine new transit…
Are There Transit Timing Variations for the Exoplanet Qatar-1b ?
Li-Hsin Su, Ing-Guey Jiang, Devesh P. Sariya +11
Motivated by the unsettled conclusion on whether there are any transit timing variations (TTVs) for the exoplanet Qatar-1b, 10 new transit light curves are presented and the TTV an…
Non-Sinusoidal Transit Timing Variations for the Exoplanet HAT-P-12b
Devesh P. Sariya, Ing-Guey Jiang, Li-Hsin Su +14
Considering the importance of investigating the transit timing variations (TTVs) of transiting exoplanets, we present a follow-up study of HAT-P-12b. We include six new light curve…
