Stars with Photometrically Young Gaia Luminosities Around the Solar System (SPYGLASS) I: Mapping Young Stellar Structures and their Star Formation Histories
Ronan Kerr, Aaron C. Rizzuto, Adam L. Kraus +1
Young stellar associations hold a star formation record that can persist for millions of years, revealing the progression of star formation long after the dispersal of the natal cl…
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…
The Green Bank Ammonia Survey: A Virial Analysis of Gould Belt Clouds in Data Release 1
Ronan Kerr, Helen Kirk, James Di Francesco +14
We perform a virial analysis of starless dense cores in three nearby star-forming regions : L1688 in Ophiuchus, NGC 1333 in Perseus, and B18 in Taurus. Our analysis takes advantage…
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…
