Metallicity of Sun-like G-stars that have exoplanets

Gurumath, S. R; Hiremath, K. M; Ramasubramanian, V (Indian Academy of Sciences, 2017-07)

By considering the physical and orbital characteristics of G type stars and their exoplanets, we examine the association between stellar mass and its metallicity that follows a power law. Similar relationship is also ...
Nearly Century-scale Variation of the Sun’s Radius

Hiremath, K. M; Rozelot, J. P; Sarp, V; Kilcik, A; Pavan, D. G; Gurumath, S. R (IOP Publishing, 2020-03-10)

The Kodaikanal Archive Program (India) is now available to the scientific community in digital form as daily digitized solar white light pictures, from 1923 to 2011. We present here the solar radius data, obtained after a ...
Solar wind associated with near equatorial coronal Hole

Hegde, M; Hiremath, K. M; Doddamani, V. H; Gurumath, S. R (2015-09)

Present study probes temporal changes in the area and radiative flux of near equatorial coronal hole associated with solar wind parameters such as wind speed, density, magnetic field and temperature. Using high temporal ...
Study of sun-like G stars and their exoplanets

Gurumath, S. R (Vellore Institute of Technology and Indian Institute of Astrophysics, 2019-05)

By employing exoplanetary physical and orbital characteristics, aim of this study is to understand the genesis, dynamics, chemical abundance and magnetic field structure of Sun-like G stars and relationship with their ...
