The Spitzer c2d Survey of Nearby Dense Cores. V. Discovery of a VeLLO in the "Starless" Dense Core L328
Chang Won Lee, Tyler L. Bourke, Philip C. Myers +8
This paper reports the discovery of a Very Low Luminosity Object (VeLLO) in the "starless" dense core L328, using the Spitzer Space Telescope and ground based observations from nea…
Probing Inward Motions in Starless Cores Using The HCN J = 1-0 Hyperfine Transitions : A Pointing Survey Toward Central Regions
Jungjoo Sohn, Chang Won Lee, Yong-Sun Park +3
We have carried out a survey toward the central regions of 85 starless cores in HCN J = 1-0 to study inward motions in the cores. Sixty-four cores were detected with HCN lines. The…
Velocity distribution of collapsing starless cores, L694-2 and L1197
Seok Ho Lee, Yong-Sun Park, Jungjoo Sohn +2
In an attempt to understand the dynamics of collapsing starless cores, we have onducted a detailed investigation of the velocity fields of two collapsing cores, L694-2 and L1197, w…
The Spitzer c2d Survey of Nearby Dense Cores: IV. Revealing the Embedded Cluster in B59
Timothy Y. Brooke, Tracy L. Huard, Tyler L. Bourke +22
Infrared images of the dark cloud core B59 were obtained with the Spitzer Space Telescope as part of the "Cores to Disks" Legacy Science project. Photometry from 3.6-70 microns ind…
The Spitzer c2d Survey of Nearby Dense Cores: II: Discovery of a Low Luminosity Object in the "Evolved Starless Core" L1521F
Tyler L. Bourke, Philip C. Myers, Neal J. Evans +12
We present Spitzer Space Telescope observations of the "evolved starless core" L1521F which reveal the presence of a very low luminosity object (L < 0.07 Lsun). The object, L1521F-…
A high resolution comparative study of the slowly contracting, starless cores, L694-2 and L1544
Jonathan Williams, Phil Myers
We present interferometric observations of N2H+(1-0) in the starless, dense core L694-2 and compare them to previously published maps of L1544. Both cores are starless, centrally c…
