Evidence for Environmental Dependence of the Upper Stellar Initial Mass Function in Orion A
Wen-hsin Hsu, Lee Hartmann, Lori Allen +4
We extend our previous study of the stellar population of L1641, the lower-density star-forming region of the Orion A cloud south of the dense Orion Nebula Cluster (ONC), with the…
Tracing High-Energy Radiation from T Tauri Stars Using Mid-Infrared Neon Emission from Disks
C. Espaillat, L. Ingleby, E. Furlan +8
High-energy radiation from T Tauri stars (TTS) influences the amount and longevity of gas in disks, thereby playing a crucial role in the creation of gas giant planets. Here we pro…
A Far-ultraviolet Atlas of Low-resolution Hubble Space Telescope Spectra of T Tauri Stars
Hao Yang, Gregory J. Herczeg, Jeffrey L. Linsky +6
We present a far-ultraviolet (FUV) spectral atlas consisting of spectra of 91 pre-main sequence stars. Most stars in this sample were observed with the Space Telescope Imaging Spec…
Short Gas Dissipation Timescales: Diskless Stars in Taurus and Chamaeleon I
L. Ingleby, N. Calvet, G. Herczeg +1
We present an Advanced Camera for Surveys/ Solar Blind Channel far-ultraviolet (FUV) study of \h2 gas in 12 weak T Tauri stars in nearby star-forming regions. The sample consists o…
On the Transitional Disk Class: Linking Observations of T Tauri Stars & Physical Disk Models
C. Espaillat, L. Ingleby, J. Hernandez +7
Two decades ago "transitional disks" described spectral energy distributions (SEDs) of T Tauri stars with small near-IR excesses, but significant mid- and far-IR excesses. Many inf…
