Imaging the water snowline around protostars with water and HCO isotopologues
Merel L. R. van 't Hoff, Daniel Harsono, Martijn L. van Gelder +7
The water snowline location in protostellar envelopes provides crucial information about the thermal structure and the mass accretion process as it can inform about the occurrence…
Gravitational time delay effects by Kerr and Kerr-Newman black holes in strong field limits
Tien Hsieh, Da-Shin Lee, Chi-Yong Lin
We study the time delay between two relativistic images due to strong gravitational lensing of the light rays caused by the Kerr and Kerr-Newman black holes. The trajectories of th…
K-band High-Resolution Spectroscopy of Embedded Massive Protostars
Tien-Hao Hsieh, Michihiro Takami, Michael S. Connelley +7
A classical paradox in high-mass star formation is that powerful radiation pressure can halt accretion, preventing further growth of a central star. Disk accretion has been propose…
Strong gravitational lensing by Kerr and Kerr-Newman black holes
Tien Hsieh, Da-Shin Lee, Chi-Yong Lin
We study the strong gravitational lensing due to the Kerr black holes with angular momentum and the Kerr-Newman black holes with additional charge . We first derive the anal…
