SPYGLASS. VII-A. The Demographics and Ages of Small Nearby Young Associations
Ronan Kerr, Facundo Peŕez Paolino, Jonathan C. Tan +5
Recent Gaia-based young stellar association surveys have revealed dozens of low-mass populations that have, until recently, been too small or sparse to detect. These populations re…
The Scuti stars of the Cep--Her Complex. I: Pulsator fraction, rotation, asteroseismic large spacings, and the relation
Simon J. Murphy, Timothy R. Bedding, Anuj Gautam +2
We identify delta Scuti pulsators amongst members of the recently-discovered Cep--Her Complex using light curves from the Transiting Exoplanet Survey Satellite (TESS). We use Gaia…
SPYGLASS. V. Spatially and Temporally Structured Star-Forming Environments in the Cepheus-Hercules Complex
Ronan Kerr, Adam L. Kraus, Daniel Krolikowski +2
Young associations record complete histories of star forming events through their demographics and dynamics, and Gaia has greatly expanded our knowledge of these associations. We p…
SPYGLASS. II. The Multi-Generational and Multi-Origin Star Formation History of Cepheus Far North
Ronan Kerr, Adam L. Kraus, Simon J. Murphy +4
Young stellar populations provide a record of past star formation, and by establishing their members' dynamics and ages, it is possible to reconstruct the full history of star form…
TESS Hunt for Young and Maturing Exoplanets (THYME) VII : Membership, rotation, and lithium in the young cluster Group-X and a new young exoplanet
Elisabeth R. Newton, Rayna Rampalli, Adam L. Kraus +36
The public, all-sky surveys Gaia and TESS provide the ability to identify new young associations and determine their ages. These associations enable study of planetary evolution by…
Massive White Dwarfs in Young Star Clusters
Harvey B. Richer, Ilaria Caiazzo, Helen Du +6
We have carried out a search for massive white dwarfs (WDs) in the direction of young open star clusters using the Gaia DR2 database. The aim of this survey was to provide robust d…
Intermediate-Mass Stars Become Magnetic White Dwarfs
Ilaria Caiazzo, Jeremy Heyl, Harvey Richer +8
When a star exhausts its nuclear fuel, it either explodes as a supernova or more quiescently becomes a white dwarf, an object about half the mass of our Sun with a radius of about…
A Massive Magnetic Helium Atmosphere White Dwarf Binary in a Young Star Cluster
Harvey B. Richer, Ronan M. Kerr, Jeremy Heyl +4
We have searched the Gaia DR2 catalogue for previously unknown hot white dwarfs in the direction of young open star clusters. The aim of this experiment was to try and extend the i…
Detection of Nitrogen gas in the Pictoris circumstellar disk
P. A. Wilson, R. Kerr, A. Lecavelier des Etangs +4
The debris disk surrounding Pictoris has a gas composition rich in carbon and oxygen, relative to solar abundances. Two possible scenarios have been proposed to explain this en…
