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…

Natural evidence for fuzzy sphere noncommutative geometry: super-Chandrasekhar white dwarfs

Surajit Kalita, T. R. Govindarajan, Banibrata Mukhopadhyay

Noncommutative geometry is one of the quantum gravity theories, which various researchers have been using to describe different physical and astrophysical systems. However, so far,…

Asymptotically flat black hole solution in modified gravity

Surajit Kalita, Banibrata Mukhopadhyay

From time to time, different observations suggest that Einstein's theory of general relativity (GR) may not be the ultimate theory of gravity. Various researchers have suggested th…

Timescales for Detecting Magnetized White Dwarfs in Gravitational Wave Astronomy

Surajit Kalita

Over the past couple of decades, researchers have predicted more than a dozen super-Chandrasekhar white dwarfs from the detections of over-luminous type Ia supernovae. It turns out…
