The Near-Ultraviolet Continuum Radiation in the Impulsive Phase of HF/GF-Type dMe Flares I: Data

Adam F. Kowalski, John P. Wisniewski, Suzanne L. Hawley +8

We present NUV flare spectra from the Hubble Space Telescope/Cosmic Origins Spectrograph during two moderate-amplitude U-band flares on the dM4e star GJ 1243. These spectra are som…

On the post-common-envelope central star of the planetary nebula NGC 2346

Alex Brown, David Jones, Henri M. J. Boffin +1

The common-envelope phase is one of the most poorly understood phases of (binary) stellar evolution, in spite of its importance in the formation of a wide-range of astrophysical ph…

Time resolved spectroscopy of dust and gas from extrasolar planetesimals orbiting WD 1145+017

Marie Karjalainen, Ernst J. W. de Mooij, Raine Karjalainen +1

Multiple long and variable transits caused by dust from possibly disintegrating asteroids were detected in light curves of WD 1145+017. We present time-resolved spectroscopic obser…

Distance, Energy, and Variability of Quasar Outflows: Two HST/COS epochs of LBQS 1206+1052

Timothy R. Miller, Nahum Arav, Xinfeng Xu +4

We analyze new HST/COS spectra for two quasar absorption outflows seen in the quasi-stellar object LBQS 1206+1052. These data cover, for the first time, absorption troughs from $S_…

The 1989 and 2015 outbursts of V404 Cygni: a global study of wind-related optical features

D. Mata Sánchez, T. Muñoz-Darias, J. Casares +19

The black hole transient V404 Cygni exhibited a bright outburst in June 2015 that was intensively followed over a wide range of wavelengths. Our team obtained high time resolution…

Dust Production and Depletion in Evolved Planetary Systems

J. Farihi, R. van Lieshout, P. W. Cauley +15

The infrared dust emission from the white dwarf GD 56 is found to rise and fall by 20% peak-to-peak over 11.2 yr, and is consistent with ongoing dust production and depletion. It i…
