ALMA View of the Infalling Envelope around a Massive Protostar in S255IR SMA1
Sheng-Yuan Liu, Yu-Nung Su, Igor Zinchenko +4
The massive young stellar object S255IR NIRS3 embedded in the star forming core SMA1 has been recently observed with a luminosity burst, which is conjectured as a disc-mediated var…
The Infall Motion in the Low-Mass Protostellar Binary NGC 1333 IRAS 4A1/4A2
Yu-Nung Su, Sheng-Yuan Liu, Zhi-Yun Li +4
We report ALMA observations of NGC 1333 IRAS 4A, a young low-mass protostellar binary, referred as 4A1 and 4A2. With multiple HCO transitions and HNC (43) observed at a reso…
JCMT POL-2 and ALMA polarimetric observations of 6000-100 au scales in the protostar B335: linking magnetic field and gas kinematics in observations and MHD simulations
Hsi-Wei Yen, Bo Zhao, I-Ta Hsieh +8
We present our analysis of the magnetic field structures from 6000 au to 100 au scales in the Class 0 protostar B335 inferred from our JCMT POL-2 observations and the ALMA archival…
Tracing magnetic field morphology using the Velocity Gradient Technique in the presence of CO self-absorption
Cheng-Han Hsieh, Yue Hu, Shih-Ping Lai +5
Probing magnetic fields in self-gravitating molecular clouds are generally difficult even with the use of the polarimetry. Based on the properties of magneto-hydrodynamic (MHD) tur…
A vehicle with a two-wheel steering system mobile in shallow dense granular media
Po-Yi Lee, Meng-Chi Tsai, I-Ta Hsieh +2
We design a vehicle with a steering system made of two independently rotatable wheels on the front. We quantify the effectiveness of the steering system in the mobility and maneuve…
The large-scale nebular pattern of a superwind binary in an eccentric orbit
Hyosun Kim, Alfonso Trejo, Sheng-Yuan Liu +5
Preplanetary nebulae and planetary nebulae are evolved, mass-losing stellar objects that show a wide variety of morphologies. Many of these nebulae consist of outer structures that…
Evidence of a Binary-Induced Spiral from an Incomplete Ring Pattern of CIT 6
Hyosun Kim, I-Ta Hsieh, Sheng-Yuan Liu +1
With the advent of high-resolution high-sensitivity observations, spiral patterns have been revealed around several asymptotic giant branch (AGB) stars. Such patterns can provide p…
