Optical Characterization of a New Young Stellar Population in the Serpens Molecular Cloud
Isa Oliveira, Bruno Merin, Klaus M. Pontoppidan +6
We report on the results of an optical spectroscopic survey designed to confirm the youth and determine the spectral types among a sample of young stellar object (YSO) candidates i…
Long-wavelength excesses of FU Orionis objects: flared outer disks or infalling envelopes?
Zhaohuan Zhu, Lee Hartmann, Nuria Calvet +3
The mid- to far-infrared emission of the outbursting FU Orionis objects has been attributed either to a flared outer disk or to an infalling envelope. We revisit this issue using d…
A Spitzer view of protoplanetary disks in the gamma Velorum cluster
Jesus Hernandez, Lee Hartmann, Nuria Calvet +4
We present new Spitzer Space Telescope observations of stars in the young ~5 Myr gamma Velorum stellar cluster. Combining optical and 2MASS photometry, we have selected 579 stars a…
