Magnetic Activity of Pre-main Sequence Stars near the Stellar-Substellar Boundary
David A. Principe, Joel H. Kastner, David Rodriguez
X-ray observations of pre-main sequence (pre-MS) stars of M-type probe coronal emission and offer a means to investigate magnetic activity at the stellar-substellar boundary. Recen…
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 ALMA Survey for Disks Orbiting Low-Mass Stars in the TW Hya Association
David R. Rodriguez, Gerrit van der Plas, Joel H. Kastner +5
We have carried out an ALMA survey of 15 confirmed or candidate low-mass (<0.2M) members of the TW Hya Association (TWA) with the goal of detecting molecular gas in the for…
