  • UVIT observation of Milky Way satellite galaxy Reticulum II 
    Divakar, D. K; Sivarani, T; Doddamani, V. H (Indian Academy of Sciences, 2021-10)
    We present the UV photometry of one of the Ultra-Faint Dwarf (UFD) Milky Way (MW) satellite galaxies, Reticulum II, using images acquired with the Ultra-Violet Imaging Telescope (UVIT) onboard AstroSat. Reticulum II is ...
  • Very low mass stellar and substellar companions to solar-like stars from MARVELS. II. A short-period companion orbiting an F star with evidence of a stellar tertiary and significant mutual inclination

    We report the discovery via radial velocity (RV) measurements of a short-period (P = 2.430420±0.000006 days) companion to the F-type main-sequence star TYC 2930-00872-1. A long-term trend in the RV data also suggests the ...

C; Wan, Xiaoke; Weaver, Benjamin A; Zhao, Bo (IOP Publishing, 2013-09)
    We report the discovery of a candidate brown dwarf (BD) or a very low mass stellar companion (MARVELS-5b) to the star HIP 67526 from the Multi-object Apache point observatory Radial Velocity Exoplanet Large-area Survey ...

P; Shelden, A; Simmons, A; Sivarani, T; van Eyken, J. C; Wan, X; Weaver, B. A; Zhao, Bo (IOP Publishing, 2013-01)
    We present an eccentric, short-period brown dwarf candidate orbiting the active, slightly evolved subgiant star TYC 2087-00255-1, which has effective temperature T eff = 5903 ± 42 K, surface gravity log (g) = 4.07 ± 0.16 ...
  • X-ray spectrum of NGC 3783 - Detection of soft excess and an emission line 
    Ghosh, K. K; Soundararajaperumal, S; Kalai Selvi, M; Sivarani, T (EDP Sciences, 1992-02)
    Results of the X-ray (0.1-10 keV) spectral analysis of the Seyfert I galaxy, NGC 3783, which was observed with EXOSAT on three epochs between 1983 and 1985, are presented here. No low energy absorption, intrinsic to the ...
