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…
Variable radio emission of neutron star X-ray binary Ser X-1 during its persistent soft state
E. C. Pattie, T. J. Maccarone, A. J. Tetarenko +3
Ser X-1 is a low mass neutron star X-ray binary and has been persistently accreting since its discovery in the 1960s. It has always been observed to be in a soft spectral state and…
A candidate magnetic helium core white dwarf in the globular cluster NGC 6397
Manuel Pichardo Marcano, Liliana E. Rivera Sandoval, Thomas J. Maccarone +5
We report a peculiar variable blue star in the globular cluster NGC 6397, using Hubble Space Telescope optical imaging. Its position in the colour-magnitude diagrams, and its spect…
A year long superoutburst from an ultracompact white dwarf binary reveals the importance of donor star irradiation
L. E. Rivera Sandoval, T. J. Maccarone, M. Pichardo Marcano
SDSS J080710+485259 is the longest period outbursting ultracompact white dwarf binary. Its first ever detected superoutburst started in November of 2018 and lasted for a year, the…
