A study of transients from ground-based surveys reveals new ultra-compact accreting white dwarf binaries

Jan Kára, Liliana Rivera Sandoval, Wendy Mendoza +5

AM CVn stars are ultra-compact semi-detached binaries consisting of a white dwarf primary and a hydrogen-depleted secondary. In this paper we present spectroscopic and photometric…

The Effect of Vera C. Rubin Observatory Cadence Selections on Kilonova Detectability

Cristina Andrade, Raiyah Alserkal, Luis Salazar Manzano +5

The discovery of the optical/infra-red counterpart (AT2017gfo) to the binary neutron star gravitational-wave detection (GW170817), which was followed by a short gamma-ray burst (GR…

A second candidate magnetic helium core white dwarf and 3 other variable white dwarfs in the globular cluster NGC 6397

Manuel Pichardo Marcano, Liliana E. Rivera Sandoval, Thomas J. Maccarone +5

Using archival Hubble Space Telescope observations, we report the discovery of four variable low-mass white dwarfs () in the globular clu…

The Temperature versus Orbital Period relation of AM CVns: Insights from their Donors

Colin W. Macrie, Liliana Rivera Sandoval, Yuri Cavecchi +2

We studied the spectral energy distribution (SED) of 22 known AM~CVns with orbital periods () larger than 35~min using multiwavelength public photometric data to estimate…

X-ray observation of the Roche-lobe filling white dwarf plus hot subdwarf system ZTF J213056.71+442046.5

S. Mereghetti, N. La Palombara, T. Kupfer +9

ZTF J213056.71+442046.5 is the prototype of a small class of recently discovered compact binaries composed of a white dwarf and a hot subdwarf that fills its Roche-lobe. Its orbita…
