In the far future long after star formation has ceased the universe will be populated by sparse degenerate remnants, mostly white dwarfs, though their ultimate fate is an open question. These white dwarfs will cool and freeze solid into black dwarfs while pycnonuclear fusion will slowly process their composition to iron-56. However, due to the declining electron fraction the Chandrasekhar limit of these stars will be decreasing and will eventually be below that of the most massive black dwarfs…

Cooling Delays from Iron Sedimentation and Iron Inner Cores in White Dwarfs
Do white dwarfs have inner cores made of iron? Neutron-rich nuclei like 56Fe experience a net gravitational force and sediment toward the core. Using new phase diagrams and molecular dynamics
Scatter-free acceleration of particles by interaction with plasma shock waves in the interstellar medium
Scatter-free acceleration is investigated for a test particle thrusted by a moving magnetized cloud in the presence of the uniform interstellar magnetic field. It is found that depending on the

The evolution and explosion of massive stars
Like all true stars, massive stars are gravitationally confined thermonuclear reactors whose composition evolves as energy is lost to radiation and neutrinos. Unlike lower-mass stars (M≲8M⊙),
TWO MASSIVE WHITE DWARFS FROM NGC 2323 AND THE INITIAL–FINAL MASS RELATION FOR PROGENITORS OF 4–6.5 M⊙*
We observed a sample of 10 white dwarf candidates in the rich open cluster NGC 2323 (M50) with the Keck Low-Resolution Imaging Spectrometer. The spectroscopy shows eight to be DA white dwarfs, with
Core crystallization and pile-up in the cooling sequence of evolving white dwarfs
TLDR
Photometry and parallax data from the Gaia satellite provide direct observational evidence of a theoretically predicted pile-up in the cooling sequence of white dwarfs, which is associated with core crystallization, and the energy released by crystallization in strongly coupled Coulomb plasmas is described.
How big can a black hole grow
I show that there is a physical limit to the mass of a black hole, above which it cannot grow through luminous accretion of gas, and so cannot appear as a quasar or active galactic nucleus (AGN). The
The evolution of iron‐core white dwarfs
Recent measurements by Hipparcos present observational evidence supporting the existence of some white dwarf (WD) stars with iron-rich core composition. In connection with this, the present paper is
Do electron-capture supernovae make neutron stars? First multidimensional hydrodynamic simulations of the oxygen deflagration
In the classical picture, electron-capture supernovae and the accretion-induced collapse of oxygen-neon white dwarfs (ONeWDs) undergo an oxygen deflagration phase before gravitational collapse
Progenitor Mass Distribution for Core-collapse Supernova Remnants in M31 and M33
Using the star formation histories (SFHs) near 94 supernova remnants (SNRs), we infer the progenitor mass distribution for core-collapse supernovae. We use Bayesian inference and model each SFH with
An Empirical Measurement of the Initial–Final Mass Relation with Gaia White Dwarfs
We use data from Gaia’s second data release (DR2) to constrain the initial–final mass relation (IFMR) for field stars with initial masses 0.9 ≲ min/M⊙ ≲ 8. Precise parallaxes have revealed
Constraining Properties of the Next Nearby Core-collapse Supernova with Multimessenger Signals
With the advent of modern neutrino and gravitational wave (GW) detectors, the promise of multimessenger detections of the next galactic core-collapse supernova (CCSN) has become very real. Such
The initial–final mass relationship of white dwarfs revisited: effect on the luminosity function and mass distribution
The initial-final mass relationship connects the mass of a white dwarf with the mass of its progenitor in the main-sequence. Although this function is of fundamental importance to several fields in
