Signs of Early-Stage Disk Growth Revealed with ALMA
Hsi-Wei Yen, Patrick M. Koch, Shigehisa Takakuwa +3
We present ALMA 1.3 mm continuum, 12CO, C18O, and SO data for the Class 0 protostars, Lupus 3 MMS, IRAS 15398-3559, and IRAS 16253-2429 at resolutions of ~100 AU. By measuring a ro…
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…
Formation of the Unequal-Mass Binary Protostars in L1551 NE by Rotationally-Driven Fragmentation
Jeremy Lim, Tomoyuki Hanawa, Paul K. H. Yeung +3
We present observations at 7 mm that fully resolve the two circumstellar disks, and a reanalyses of archival observations at 3.5 cm that resolve along their major axes the two ioni…
The Sunyaev-Zel'dovich Effect at Five Arc-seconds: RXJ1347.5-1145 Imaged by ALMA
T. Kitayama, S. Ueda, S. Takakuwa +12
We present the first image of the thermal Sunyaev-Zel'dovich effect (SZE) obtained by the Atacama Large Millimeter/submillimeter Array (ALMA). Combining 7-m and 12-m arrays in Band…
Rotationally-Driven Fragmentation for the Formation of the Binary Protostellar System L1551 IRS 5
Jeremy Lim, Paul K. H. Yeung, Tomoyuki Hanawa +3
Either bulk rotation or local turbulence is widely invoked to drive fragmentation in collapsing cores so as to produce multiple star systems. Even when the two mechanisms predict d…
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…
