A Systematic Search for Molecular Outflows Toward Candidate Low-Luminosity Protostars and Very Low Luminosity Objects
Kamber R. Schwarz, Yancy L. Shirley, Michael M. Dunham
We present a systematic single-dish search for molecular outflows toward a sample of 9 candidate low-luminosity protostars and 30 candidate Very Low Luminosity Objects (VeLLOs; L_i…
CO2 Ice toward Low-luminosity, Embedded Protostars: Evidence for Episodic Mass Accretion via Chemical History
Hyo Jeong Kim, Neal J. Evans, Michael M. Dunham +2
We present Spitzer IRS spectroscopy of CO2 ice bending mode spectra at 15.2 micrometer toward 19 young stellar objects with luminosity lower than 1 Lsun (3 with luminosity lower th…
Revealing The Millimeter Environment of the New FU Orionis Candidate HBC722 with the Submillimeter Array
Michael M. Dunham, Hector G. Arce, Tyler L. Bourke +3
We present 230 GHz Submillimeter Array continuum and molecular line observations of the newly discovered FUor candidate HBC722. We report the detection of seven 1.3 mm continuum so…
SMA and Spitzer Observations of Bok Glouble CB17: A Candidate First Hydrostatic Core?
Xuepeng Chen, Hector G. Arce, Michael M. Dunham +5
We present high angular resolution SMA and Spitzer observations toward the Bok globule CB17. SMA 1.3mm dust continuum images reveal within CB17 two sources with an angular separati…
Discovery of A Binary System in IRAM 04191+1522
Xuepeng Chen, Hector G. Arce, Michael M. Dunham +1
We present high angular resolution observations of the Class 0 protostar IRAM04191+1522, using the Submillimeter Array (SMA). The SMA 1.3 mm continuum images reveal within IRAM0419…
