Confirmation of a Second Propeller: A High-Inclination Twin of AE~Aquarii
Peter Garnavich, Colin Littlefield, R. M. Wagner +4
For decades, AE Aquarii (AE Aqr) has been the only cataclysmic variable star known to contain a magnetic propeller: a persistent outflow whose expulsion from the binary is powered…
Discovery of Highly Blueshifted Broad Balmer and Metastable Helium Absorption Lines in a Tidal Disruption Event
T. Hung, S. B. Cenko, Nathaniel Roth +25
We report the discovery of non-stellar hydrogen Balmer and metastable helium absorption lines accompanying a transient, high-velocity (0.05) broad absorption line (BAL) system i…
Phase-Resolved Spectroscopy of Gaia14aae: Line Emission From Near the White Dwarf Surface
M. J. Green, T. R. Marsh, D. Steeghs +8
AM CVn binaries are a class of ultracompact, hydrogen-deficient binaries, each consisting of a white dwarf accreting helium-dominated material from a degenerate or semi-degenerate…
High-Speed Photometry of Gaia14aae: An Eclipsing AM CVn That Challenges Formation Models
M. J. Green, T. R. Marsh, D. T. H. Steeghs +19
AM CVn-type systems are ultra-compact, hydrogen-deficient accreting binaries with degenerate or semi-degenerate donors. The evolutionary history of these systems can be explored by…
The OmegaWhite survey for short-period variable stars - V. Discovery of an ultracompact hot subdwarf binary with a compact companion in a 44 minute orbit
T. Kupfer, G. Ramsay, J. van Roestel +20
We report the discovery of the ultracompact hot subdwarf (sdOB) binary OW J074106.0-294811.0 with an orbital period of P min, making it the…
