Detection of lithium in nearby young late-M dwarfs
N. Phan-Bao, M. S. Bessell, D. Nguyen-Thanh +4
Late M-type dwarfs in the solar neighborhood include a mixture of very low-mass stars and brown dwarfs which is difficult to disentangle due to the lack of constraints on their age…
Stacking Spectra in Protoplanetary Disks: Detecting Intensity Profiles from Hidden Molecular Lines in HD 163296
Hsi-Wei Yen, Patrick M. Koch, Hauyu Baobab Liu +4
We introduce a new stacking method in Keplerian disks that (1) enhances signal-to-noise ratios (S/N) of detected molecular lines and (2) that makes visible otherwise undetectable w…
Angular momentum loss in the envelope-disk transition region of HH 111 protostellar system: evidence for magnetic braking?
Chin-Fei Lee, Hsiang-Chih Hwang, Zhi-Yun Li
HH 111 is a Class I protostellar system at a distance of ~ 400 pc, with the central source VLA 1 associated with a rotating disk deeply embedded in a flattened envelope. Here we pr…
A study of the wiggle morphology of HH 211 through numerical simulations
Anthony Moraghan, Chin-Fei Lee, Po-Sheng Huang +1
Recent high-resolution high-sensitivity observations of protostellar jets have shown many to possess deviations to their trajectories. HH 211 is one such example where sub-mm obser…
Gas Gaps in the Protoplanetary Disk around the Young Protostar HL Tau
Hsi-Wei Yen, Hauyu Baobab Liu, Pin-Gao Gu +4
We have analyzed the HCO+ (1-0) data of the Class I-II protostar, HL Tau, obtained from the Atacama Large Millimeter/Submillimeter Array long baseline campaign. We generated the HC…
The Shaping of the Multipolar Pre-Planetary Nebula CRL 618 by Multi-directional Bullets
Po-Sheng Huang, Chin-Fei Lee, Anthony Moraghan +1
In order to understand the formation of the multipolar structures of the pre-planetary nebula (PPN) CRL 618, we perform 3D simulations using a multi-directional bullet model. The o…
