A Novel Survey for Young Substellar Objects with the W band Filter.V. IC 348 and Barnard 5 in the Perseus Cloud
Bhavana Lalchand, Wen-Ping Chen, Beth A. Biller +10
We report the discovery of substellar objects in the young star cluster IC 348 and the neighboring Barnard 5 dark cloud, both at the eastern end of the Perseus star-forming complex…
Diagnosing FUor-like Sources: The Parameter Space of Viscously Heated Disks in the Optical and Near-IR
Hanpu Liu, Gregory J. Herczeg, Doug Johnstone +8
FU Ori type objects (FUors) are decades-long outbursts of accretion onto young stars that are strong enough to viscously heat disks so that the disk outshines the central star. We…
Tracers of Dense Gas in the Outer Galaxy
Sudeshna Patra, Neal J. Evans, Kee-Tae Kim +5
We have mapped HCN and HCO (J = 1 0) line emission toward a sample of seven star-forming regions (with 12 + log[O/H] range from 8.34 to 8.69) in the outer Milky Way (Ga…
Revealing the dust grain polarization properties as a function of extinction and distance towards NGC 1893
N. Bijas, Chakali Eswaraiah, Jia-Wei Wang +5
Dust polarization observations at optical wavelengths help to understand the dust grain properties and trace the plane-of-the-sky component of the magnetic field. In this study, we…
