A kinematically unbiased, all-sky search for nearby, young, low-mass stars
Alexander S. Binks, Matthieu Chalifour, Joel H. Kastner +6
The past two decades have seen dramatic progress in our knowledge of the population of young stars of age Myr that lie within pc of the Sun. These nearby, young sta…
Is the Young Star RZ Piscium Consuming Its Own (Planetary) Offspring?
K. M. Punzi, J. H. Kastner, C. Melis +4
The erratically variable star RZ Piscium (RZ Psc) displays extreme optical dropout events and strikingly large excess infrared emission. To ascertain the evolutionary status of thi…
Nearby Young, Active, Late-type Dwarfs in Gaia's First Data Release
Joel H. Kastner, Germano Sacco, David Rodriguez +3
The Galex Nearby Young Star Survey (GALNYSS) has yielded a sample of 2000 UV-selected objects that are candidate nearby (150 pc), young (age 10--1…
M Stars in the TW Hya Association: Stellar X-rays and Disk Dissipation
Joel H. Kastner, David A. Principe, Kristina Punzi +4
To investigate the potential connection between the intense X-ray emission from young, low-mass stars and the lifetimes of their circumstellar, planet-forming disks, we have compil…
Constraining X-ray-Induced Photoevaporation of Protoplanetary Disks Orbiting Low-Mass Stars
Kristina M. Punzi, Joel H. Kastner, David Rodriguez +2
Low-mass, pre-main sequence stars possess intense high-energy radiation fields as a result of their strong stellar magnetic activity. This stellar UV and X-ray radiation may have a…
An Unbiased 1.3 mm Emission Line Survey of the Protoplanetary Disk Orbiting LkCa 15
Kristina M. Punzi, Pierre Hily-Blant, Joel H. Kastner +2
The outer (>30 AU) regions of the dusty circumstellar disk orbiting the ~2-5 Myr-old, actively accreting solar analog LkCa 15 are known to be chemically rich, and the inner disk ma…
Unbiased mm-wave Line Surveys of TW Hya and V4046 Sgr: The Enhanced C2H and CN Abundances of Evolved Protoplanetary Disks
Joel H. Kastner, Pierre Hily-Blant, David R. Rodriguez +2
We have conducted the first comprehensive mm-wave molecular emission line surveys of the evolved circumstellar disks orbiting the nearby T Tauri stars TW Hya and V4046 Sgr AB. Both…
