In this paper we review the current status of research on the observational and theoretical
characteristics of isolated and binary magnetic white dwarfs (MWDs). Magnetic fields of …

▪ Abstract Since the discovery of the first bona-fide brown dwarfs and extra-solar planets in
1995, the field of low-mass stars and substellar objects has progressed considerably, both …

With the advent of more sensitive all-sky instruments, the transient universe is being probed
in greater depth than ever before. Taking advantage of available resources, we have …

ABSTRACT I consider quasi-periodic eruptions (QPEs) from galaxy nuclei. All the known
cases fit naturally into a picture of accretion from white dwarfs (WDs) in highly eccentric …

We investigate models for the class of ultraluminous nonnuclear X-ray sources (ie,
ultraluminous compact X-ray sources [ULXs]) seen in a number of galaxies and probably …

Outburst mechanisms of dwarf novae are discussed. There is a rich variety in outburst
behaviors of nonmagnetic cataclysmic variable stars, starting from nonoutbursting nova-like …

The class of cataclysmic variables called Polars, or AM Her systems, is comprehensively
reviewed. Each part of these systems, from the two underlying stars, to the accretion region …

Abstract Active Galactic Nuclei (henceforth AGN) have been observed assiduously
throughout the electromagnetic spectrum over the past 30 years and we know much about …

We have used the Robert C. Byrd Green Bank Telescope to time nine previously known
pulsars without published timing solutions in the globular clusters (GCs) M62, NGC 6544 …

Eclipsing binary millisecond pulsars (MSPs; the so-called black widows and redbacks) can
provide important information about accretion history, pulsar irradiation of their companion …
