Context. A large number of low-mass (<∼0.20 M ) helium white dwarfs (He WDs) have recently been discovered. The majority of these are orbiting another WD or a millisecond pulsar (MSP) in a close binary system; a few examples are found to show pulsations or to have a main-sequence star companion. There appear to be discrepancies between the current theoretical modelling of such lowmass He WDs and a number of key observed cases, indicating that their formation scenario yet remains to be fully…

Novel modelling of ultracompact X-ray binary evolution - stable mass transfer from white dwarfs to neutron stars
Tight binaries of helium white dwarfs (He WDs) orbiting millisecond pulsars (MSPs) will eventually "merge" due to gravitational damping of the orbit. The outcome has been predicted to be the
Models of low-mass helium white dwarfs including gravitational settling, thermal and chemical diffusion, and rotational mixing
A large number of extremely low-mass helium white dwarfs (ELM WDs) have been discovered in recent years. The majority of them are found in close binary systems suggesting they are formed either
Investigating the Stability of Mass Transfer in Neutron Star–helium White Dwarf Binaries
Neutron star–helium white dwarf (NS+He WD) binaries are important evolutionary products of close-orbit binary star systems. They are often observed as millisecond pulsars and may continue evolving
A Model of the Pulsating Extremely Low-Mass White Dwarf Precursor WASP 0247-25B
We present an analysis of the evolutionary and pulsation properties of the extremely low-mass white dwarf precursor (B) component of the double-lined eclipsing system WASP 0247−25. Given that the

Context. Some globular clusters host multiple stellar populations with different chemical abundance patterns. This is particularly true for ? Centauri, which shows clear evidence of a helium-enriched
Asymmetrical Mass Ejection from Proto-white Dwarfs and the Formation of Eccentric Millisecond Pulsar Binaries
Binary millisecond pulsars (MSPs) are believed to have descended from low-mass X-ray binaries (LMXBs), which have experienced substantial mass transfer and tidal circularization. Therefore, they

New full evolutionary sequences of H- and He-atmosphere massive white dwarf stars using mesa
We explore the evolution of hydrogen-rich and hydrogen-deficient white dwarf stars with masses between 1.012 and 1.307 Msun, and initial metallicity of Z=0.02. These sequences are the result of main
