Unveiling the nature of barium stars. I. Asteroseismic masses and the evolutionary link between Ba dwarfs and giants
Lupamudra Sarmah, Yerra Bharat Kumar, Simon W. Campbell +2
Barium star systems are excellent sites for studying AGB nucleosynthesis, binary evolution, and mass transfer processes. However, an accurate estimation of their fundamental stella…
Effects of modified gravity on microscopic properties and cooling timescale of white dwarfs
Aneta Wojnar, Surajit Kalita, Lupamudra Sarmah
There are currently two open questions in white dwarf physics: why are massive dwarfs observed less often in astronomical surveys, and why have not any super-Chandrasekhar white dw…
Metric-affine effects in crystallization processes of white dwarfs
Surajit Kalita, Lupamudra Sarmah, Aneta Wojnar
We analyze the effects of modified gravity on specific heats of electrons and ions, Debye temperature, crystallization process, and cooling mechanism in white dwarfs. We derive the…
Cooling Process of White Dwarf Stars in Palatini Gravity
Surajit Kalita, Lupamudra Sarmah, Aneta Wojnar
A simple cooling model of white dwarf stars is re-analyzed in Palatini gravity. Modified gravity affects the white dwarf structures and consequently their ages. We find that…
Weak-field limit of gravity to unify peculiar white dwarfs
Surajit Kalita, Lupamudra Sarmah
In recent years, the idea of sub- and super-Chandrasekhar limiting mass white dwarfs (WDs), which are potential candidates to produce under- and over-luminous type Ia supernovae, r…
Stability criterion for white dwarfs in Palatini gravity
Lupamudra Sarmah, Surajit Kalita, Aneta Wojnar
Recent observations of several peculiar over- and under-luminous type Ia supernovae infer indirect evidence for the violation of the Chandrasekhar mass-limit by suggesting the exis…
