Soft X-ray spectral variability of AM Herculis
, 2008 Context. Polars (AM Herculis binaries) are a prominent class of bright soft X-ray sources, many of which were discovered with ROSAT. Aims. We present a homogenous analysis of all the pointed ROSAT PSPC observations of polars subdivided into ...

Time-resolved spectroscopy of the AM Herculis-type binary systems QQ VUL and EF ERI
, 1998 Cataclysmic variable stars (CVs) are interacting binary systems. One of the stars (referred to as the primary) is a white dwarf, the other (referred to as the secondary) is usually a late main sequence star such as a red dwarf.

, 2020 We report on XMM-Newton and NuSTAR X-ray observations of the prototypical polar, AM Herculis, supported by ground-based photometry and spectroscopy, all obtained in high accretion states. In 2005, AM Herculis was in its regular mode of accretion, showing

, 2021 The metallic-line (Am) stars are chemically peculiar A and early F stars that show weak spectral lines of Ca K and Sc and strong iron-group features compared to their hydrogen-line spectral type.

Equilibria and oscillations of magnetised neutron stars
, 2010 We investigate equilibrium configurations and oscillation spectra of neutron stars,modelled as rotating magnetised fluid bodies in Newtonian gravity. We also explorethe idea that these model neutron stars could have dynamics analogous to rigid-bodyfree ...

Implications for compact stars of a soft nuclear equation of state from heavy-ion data [PDF]
, 2012 We study the implications on compact star properties of a soft nuclear equation of state determined from kaon production at subthreshold energies in heavy-ion collisions.

Signals of the QCD Phase Transition in the Heavens [PDF]
, 2007 The modern phase diagram of strongly interacting matter reveals a rich structure at high-densities due to phase transitions related to the chiral symmetry of quantum chromodynamics (QCD) and the phenomenon of color superconductivity.

Magnetic fields in A stars besides Ap stars
, 2014 I review ongoing efforts to understand the incidence of magnetism in intermediate-mass stars that are different from the magnetic Ap stars. This includes the search for magnetic fields in chemically peculiar stars of the Am and HgMn types as well as in ...

Hubble space telescope parallaxes of AM CVn stars and astrophysical consequences [PDF]
, 2007 We present absolute parallaxes and relative proper motions for five AM CVn stars, which we obtained using the Fine Guidance Sensors on board the Hubble Space Telescope. Our parallax measurements translate into distances dAM CVn = 606(-93)(+135) pc, d(HP)
