Far-Ultraviolet H_2 Emission from Circumstellar Disks (2009)
Ingleby, Laura, Calvet, Nuria, Bergin, Edwin, Yerasi, Ashwin, Espaillat, Catherine, Herczeg, Gregory, ...
We analyze the far-ultraviolet (FUV) spectra of 33 classical T Tauri stars (CTTS), including 20 new spectra obtained with the Advanced Camera for Surveys Solar Blind Channel (ACS/SBC) on the Hubble...

Molecular Line Observations of Infrared Dark Clouds II: Physical Conditions (2009)
Gibson, David, Plume, Rene, Bergin, Edwin, Ragan, Sarah, Evans, Natalie
Using a source selection biased towards high mass star forming regions, we used a Large Velocity Gradient (LVG) code to calculate the H2 densities and CS column densities for a sample of Midcourse...
Young stellar clusters and star formation throughout the Galaxy (2009)
Feigelson, Eric, Adams, Fred, Allen, Lori, Bergin, Edwin, Bally, John, Balog, Zoltan, ...
Most stars are born in rich young stellar clusters (YSCs) embedded in giant molecular clouds. The most massive stars live out their short lives there, profoundly influencing their natal environments...

Probing the Dust and Gas in the Transitional Disk of CS Cha with Spitzer (2007)
Espaillat, Catherine, Calvet, Nuria, D'Alessio, Paola, Bergin, Edwin, Hartmann, Lee, Watson, Dan, ...
Here we present the Spitzer IRS spectrum of CS Cha, a member of the ~2 Myr old Chamaeleon star-forming region, which reveals an optically thick circumstellar disk truncated at ~43 AU, the largest...
Bergin, Edwin, Calvet, Nuria, D'Alessio, Paola, Herczeg, Gregory J.
We show in this Letter that the spectral details of the FUV radiation fields have a large impact on the chemistry of protoplanetary disks surrounding T Tauri stars. We show that the strength of a...
A New Probe of the Planet-Forming Region in T Tauri Disks (1998)
Bergin, Edwin, Calvet, Nuria, Sitko, Michael L., Abgrall, Herve, D'Alessio, Paola, Herczeg, Gregory J., ...
We present new observations of the far-ultraviolet (FUV; 1100 2200 A) radiation field and the near- to mid-IR (3-13.5 micron) spectral energy distribution (SED) of a sample of T Tauri stars selected...
