When the primary star in a close binary system evolves into a giant and engulfs its
companion, its core and the companion temporarily orbit each other inside a common …

Massive stars play a major role in the evolution of their host galaxies and serve as important
probes of the distant Universe. It has been established that the majority of massive stars …

Fast radio bursts (FRBs) are millisecond-duration events detected from beyond the Milky
Way. FRB emission characteristics favour highly magnetized neutron stars, or magnetars, as …

Neutron stars are natural physical laboratories allowing us to study a plethora of
phenomena in extreme conditions. In particular, these compact objects can have very strong …

Massive stars (those≥ 8 solar masses at formation) have radiative envelopes that cannot
sustain a dynamo, the mechanism that produces magnetic fields in lower-mass stars …

The origin of magnetic fields in white dwarfs remains a fundamental unresolved problem in
stellar astrophysics. In particular, the very different fractions of strongly (more than about a …

Gaia BH1, the first quiescent black hole (BH) detected from Gaia data, poses a challenge to
most binary evolution models: its current mass ratio is≈ 0.1, and its orbital period seems to …

The majority of massive stars are expected to exchange mass or merge with a companion
during their lives. This immediately implies that most supernovae (SNe) are from such post …

Context. The majority of massive stars are part of binary systems. In about a quarter of these,
the companions are so close that mass transfer occurs while they undergo core hydrogen …
