white dwarfs within 40 pc III: spectroscopic observations of new candidates in the southern hemisphere
Mairi W. O'Brien, P. -E. Tremblay, N. P. Gentile Fusillo +31
We present a spectroscopic survey of 248 white dwarf candidates within 40 pc of the Sun; of these 244 are in the southern hemisphere. Observations were performed mostly with the Ve…
KELT-9 and its ultra-hot Jupiter: stellar parameters, composition, and planetary pollution
Mihkel Kama, Colin P. Folsom, Adam S. Jermyn +1
KELT-9b is an ultra-hot Jupiter observed to be undergoing extreme mass loss. Its A0-type host star has a radiative envelope, which makes its surface layers prone to retaining recen…
A Transient "Changing-look'' Active Galactic Nucleus Resolved on Month Timescales from First-year Sloan Digital Sky Survey V Data
Grisha Zeltyn, Benny Trakhtenbrot, Michael Eracleous +32
We report the discovery of a new ``changing-look'' active galactic nucleus (CLAGN) event, in the quasar SDSS J162829.17+432948.5 at z=0.2603, identified through repeat spectroscopy…
The effects of surface fossil magnetic fields on massive star evolution: IV. Grids of models at Solar, LMC, and SMC metallicities
Z. Keszthelyi, A. de Koter, Y. Götberg +12
Magnetic fields can drastically change predictions of evolutionary models of massive stars via mass-loss quenching, magnetic braking, and efficient angular momentum transport, whic…
An extended [CII] halo around a massive star-forming galaxy at z = 5.3
T. S. Lambert, A. Posses, M. Aravena +8
High-redshift observations are often biased towards massive and bright galaxies that are not necessarily representative of the full population. In order to accurately study galaxy…
A dense mini-Neptune orbiting the bright young star HD 18599
Jose I. Vines, James S. Jenkins, Zaira Berdiñas +23
Very little is known about the young planet population because the detection of small planets orbiting young stars is obscured by the effects of stellar activity and fast rotation…
