Five New Sirius-Like White Dwarf + Main Sequence Star Systems with MagAO-X
Logan A. Pearce, Jared R. Males, Sebastiaan Y. Haffert +20
Most known white dwarfs in multiple systems with main sequence stars have been discovered with M-type companions, because the white dwarf causes detectable UV excess and bluer colo…
The Proxima Centauri Campaign -- First Constraints On Millimeter Flare Rates from ALMA
Kiana Burton, Meredith A. MacGregor, Rachel A. Osten +6
Proxima Centauri (Cen) has been the subject of many flaring studies due to its proximity and potential to host habitable planets. The discovery of millimeter flares from this M dwa…
A cool, magnetic white dwarf accreting planetary debris
Stephane Vennes, Adela Kawka, Beth L. Klein +3
We present an analysis of spectroscopic data of the cool, highly magnetic and polluted white dwarf 2MASS J0916-4215. The atmosphere of the white dwarf is dominated by hydrogen, but…
The surprising evolution of the shadow on the TW Hya disk
J. Debes, R. Nealon, R. Alexander +8
We report new total intensity visible light high contrast imaging of the TW Hya disk taken with the Space Telescope Imaging Spectrograph (STIS) on the Hubble Space Telescope (HST).…
HIP 67506 C: MagAO-X Confirmation of a New Low-Mass Stellar Companion to HIP 67506 A
Logan A. Pearce, Jared R. Males, Sebastiaan Y. Haffert +17
We report the confirmation of HIP 67506 C, a new stellar companion to HIP 67506 A. We previously reported a candidate signal at 2/D (240~mas) in L in MagAO/Clio imagi…
New chondritic bodies identified in eight oxygen-bearing white dwarfs
Alexandra E. Doyle, Beth L. Klein, Patrick Dufour +8
We present observations and analyses of eight white dwarf stars that have accreted rocky material from their surrounding planetary systems. The spectra of these helium-atmosphere w…
