KL Dra as a Benchmark Laboratory for Accretion-Disk Physics: Constraints from TESS and Ground-Based Surveys
Luis E. Salazar Manzano, Liliana E. Rivera Sandoval, Jean-Marie Hameury +4
We present the longest-term optical analysis of the AM CVn system KL Dra using years of monitoring from TESS and wide-field ground-based surveys. The continuous TESS cover…
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…
Massive Double White Dwarf Binary Mergers from the Moon: Extending the Reach of Multi-messenger Astrophysics
Manuel Pichardo Marcano, Anjali B. Yelikar, Karan Jani
We explore the potential of lunar-based gravitational-wave detectors to broaden the multi-messenger astrophysics landscape by detecting mergers of massive () do…
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…
