Age Analysis of Extrasolar Planets: Insight from Stellar Isochrone Models

Swastik, C; Banyal, R. K; Narang, Mayank; Unni, Athira; Sivarani, T (American Astronomical Society, 2024-06-03)

There is growing evidence from stellar kinematics and galactic chemical evolution suggesting that giant planets (MP 0.3MJ) are relatively young compared to the most commonly occurring population of small planets (MP < ...
Critical Analysis of Tess Transit Photometric Data: Improved Physical Properties for Five Exoplanets

Saha, Suman; Sengupta, S (2021-11-01)

We present improved physical parameters for four hot Jupiters: KELT-7 b, HAT-P-14 b, WASP-29 b, WASP-95 b, and a hot Neptune: WASP-156 b, by performing critical and rigorous analysis of the time-series observations from the ...
Multiband transit follow-up observations of five hot Jupiters with critical noise treatments: improved physical properties

Saha, Suman; Chakrabarty, Aritra; Sengupta, S (IOP Publishing, 2021-07-01)

The most challenging limitation in transit photometry arises from the noises in the photometric signal. In particular, the ground-based telescopes are heavily affected by the noise due to perturbation in the Earth’s ...
Revisiting the Transit Timing Variations in the TrES-3 and Qatar-1 Systems with TESS Data

Mannaday, Vineet Kumar; Thakur, Parijat; Southworth, John; Jiang, Ing-Guey; Sahu, D. K; Mancini, L; Vanko, M; Kundra, Emil; Gajdos, Pavol; A-thano, Napaporn; Sariya, Devesh P; Yeh, Li-Chin; Griv, Evgeny; Mkrtichian, David; Shlyapnikov, Aleksey (American Astronomical Society, 2022-11-01)

We present and analyze 58 transit light curves of TrES-3b and 98 transit light curves of Qatar-1b, observed by the Transiting Exoplanet Survey Satellite, plus two transit light curves of Qatar-1b, observed by us, using a ...
