  • Are there transit timing variations for the exoplanet qatar-1b? 
    Su, Li-Hsin; Jiang, Ing-Guey; Sariya, Devesh P; Lee, Chiao-Yu; Yeh, Li-Chin; Mannaday, Vineet Kumar; Thaku, Parijat; Chand, Swadesh; Shlyapnikov, A. A; Moskvin, V. V; Ignatov, Vladimir; Mkrtichian, David; Griv, Evgeny; Sahu, D. K (IOP Publishing, 2021-03-01)
    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 a TTV analysis with a baseline of 1400 epochs is ...
  • A Comprehensive Study of Five Intermediate-age Pismis (2, 3, 7, 12, 15) Clusters Using Photometric and Astrometric Data from Gaia EDR3 
    Bisht, D; Zhu, Qingfeng; Elsanhoury, W. H; Yadav, R. K. S; Rangwal, Geeta; Sariya, Devesh P; Durgapal, Alok; Jiang, Ing-Guey (American Astronomical Society, 2022-11-01)
    Open clusters are groups of stars that form simultaneously; hence, these are excellent probes to test theories of star formation, stellar evolution, and dynamics in the Milky Way disk. We carry out a detailed photometric ...
  • A Deep Investigation of Two Poorly Studied Open Clusters Haffner 22 and Melotte 71 in the Gaia era 
    Bisht, D; Zhu, Qingfeng; Yadav, R. K. S; Rangwal, Geeta; Sariya, Devesh P; Durgapal, Alok; Jiang, Ing-Guey (IOP Publishing, 2022-04)
    This paper presents a deep investigation of two open clusters, Haffner 22 and Melotte 71, using astrometric and photometric data from Gaia EDR3. We identified 382 and 597 most probable cluster members with membership ...
  • A Gaia based analysis of open cluster Berkeley 27 
    Sariya, Devesh P; Jiang, Ing-Guey; Bisht, D; Yadav, R. K. S; Rangwal, Geeta (Elsevier B.V, 2023-01)
    In this paper, we have used the Gaia’s Data Release-3 (DR3) data to study an intermediate-age open cluster Berkeley 27 (Be 27). A total of 131 most probable cluster members are picked within the cluster’s radius based ...
  • 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 ...
  • The Transit Timing and Atmosphere of Hot Jupiter HAT-P-37b 
    A-thano, Napaporn; Jiang, Ing-Guey; Awiphan, Supachai; Rattanamala, Ronnakrit; Su, Li-Hsin; Hengpiya, Torik; Sariya, Devesh P.; Yeh, Li-Chin; Shlyapnikov, A. A.; Gorbachev, Mark A.; Rublevski, Alexey N.; Mannaday, Vineet Kumar; Thakur, Parijat; Sahu, D. K; Mkrtichian, David; Griv, Evgeny (American Astronomical Society, 2022-02-01)
    We perform transit timing variation (TTV) and transmission spectroscopy analyses of the planet HAT-P-37b, which is a hot Jupiter orbiting a G-type star. Nine new transit light curves are obtained and analyzed together with ...
