A Survey and Analysis of Spitzer Infrared Spectrograph Spectra of T Tauri Stars in Taurus
- E. Furlan, L. Hartmann, +20 authors Ithaca College
- Physics
- 1 August 2006
We present mid-infrared spectra of T Tauri stars in the Taurus star-forming region obtained with the Spitzer Infrared Spectrograph (IRS). For the first time, the 5–36 � m spectra of a large sample of… Expand
The Disk Population of the Taurus Star-Forming Region
- K. Luhman, P. Allen, C. Espaillat, L. Hartmann, N. Calvet
- Physics
- 29 November 2009
We have analyzed nearly all images of the Taurus star-forming region at 3.6, 4.5, 5.8, 8.0, and 24??m that were obtained during the cryogenic mission of the Spitzer Space Telescope (46 deg2) and have… Expand
The Spitzer Space Telescope Survey of the Orion A and B Molecular Clouds. I. A Census of Dusty Young Stellar Objects and a Study of Their Mid-infrared Variability
- S. Megeath, R. Gutermuth, +10 authors G. Fazio
- Physics
- 18 September 2012
We present a survey of the Orion A and B molecular clouds undertaken with the IRAC and MIPS instruments on board Spitzer. In total, five distinct fields were mapped, covering 9 deg^2 in five mid-IR… Expand
Measuring accretion in young substellar objects: Approaching the planetary mass regime
- J. Muzerolle, K. Luhman, C. Briceño, L. Hartmann, N. Calvet
- Physics
- 1 February 2005
We present observations of Hα emission-line profiles taken at Magellan Observatory for a sample of 39 young low-mass stars and brown dwarfs in the Taurus and Chamaeleon I star-forming regions. We… Expand
Magnetospheres and Disk Accretion in Herbig Ae/Be Stars
- J. Muzerolle, P. d’Alessio, N. Calvet, L. Hartmann
- Physics
- 1 September 2004
We present evidence of magnetically mediated disk accretion in Herbig Ae/Be stars. Magnetospheric accretion models of Balmer and sodium profiles calculated with appropriate stellar and rotational… Expand
Initial Results from the Spitzer Young Stellar Cluster Survey
- S. Megeath, L. Allen, +8 authors U. Arizona
- Physics
- 1 June 2004
We report initial results from IRAC observations of four young stellar clusters. These regions are part of a larger Spitzer Space Telescope survey of 31 young stellar groups and clusters within 1 kpc… Expand
Keck Interferometer Observations of Classical and Weak-line T Tauri Stars
