▪ Abstract Low-mass particles, such as neutrinos, axions, other Nambu-Goldstone bosons,
and gravitons, are produced in the hot and dense interior of stars. Therefore, astrophysical …

The evolution of white dwarfs is essentially a gravothermal process of cooling in which the
basic ingredients for predicting their evolution are well identified, although not always well …

For centuries the heavens have been a natural laboratory to test the classical laws of motion,
and more recently to test Einstein's theory of gravity. Today, astrophysics has become a vast …

Several stellar systems (white dwarfs, red giants, horizontal branch stars and possibly the
neutron star in the supernova remnant Cassiopeia A) show a mild preference for a non …

We review the physics potential of a next generation search for solar axions: the
International Axion Observatory (IAXO). Endowed with a sensitivity to discover axion-like …

We present a summary of what is currently known about the three distinct families of isolated
pulsating white dwarfs. These are the GW Vir stars (He/C/O-atmosphere stars with T eff≃ …

The white dwarf disk luminosity function is explored using observational results of Liebert et
al.(1988, 1989) as a template for comparison, and the cooling curves of Wood (1990, 1991) …

The discovery of the first extra-solar planet surrounding a main-sequence star was
announced in 1995, based on very precise radial velocity (Doppler) measurements. A total …

We employ a state-of-the-art asteroseismological model of G117− B15A, the archetype of
the H-rich atmosphere (DA) white dwarf pulsators (also known as DAV or ZZ Ceti variables) …

We report the detection of orbital decay in the 12.75-minute, detached binary white dwarf
(WD) SDSS J065133. 338+ 284423.37 (hereafter J0651). Our photometric observations …
