HOPS-288: A Laboratory for Complex Organics in Proto-multiple Systems
Shih-Ying Hsu, Nadia M. Murillo, Chin-Fei Lee +21
Complex organic molecules (COMs) in young stellar objects (YSOs) have attracted significant attention in recent years due to their potential connection to pre-biotic chemistry and…
Constraining Active Galactic Nucleus Jets with Spectrum and Core Shift: The Case of M87
Kouichi Hirotani, Hsien Shang, Ruben Krasnopolsky +3
We analytically model stationary and axisymmetric active galactic nucleus jets, assuming energy conservation along each magnetic flux tube. Using very-long-baseline interferometry…
Resistive Collapse of 2D Non-rotating Magnetized Isothermal Toroids: Formation of Pseudodisks
Ya-Chi Wang, Hsien Shang, Ruben Krasnopolsky
The collapse of singular magnetized toroids (Li & Shu 1996) is a natural representation of an early phase in star formation, bridging the prestellar and protostellar phases of the…
R-JET: A postprocessing code for radiative transport in relativistic jets
Kouichi Hirotani, Hsien Shang, Ruben Krasnopolsky +1
We describe a post-processing radiative transport code for computing the spectra, the coreshift, and the surface-brightness distribution of special relativistic jets with arbitrary…
How Does a Protostar Form by Magnetized Gravitational Collapse?
Indrani Das, Hsien Shang, Ruben Krasnopolsky
Star formation through the dynamical magnetized collapse remains an active area of astrophysical research. We carry out a comprehensive exploration on the magnetized gravitational…
ALMA Survey of Orion Planck Galactic Cold Clumps (ALMASOP): Nested Morphological and Kinematic Structures of Outflows Revealed in SiO and CO Emission
Chun-Fan Liu, Hsien Shang, Doug Johnstone +22
The Atacama Large Millimeter/submillimeter Array Survey of Orion Planck Galactic Cold Clumps (ALMASOP) reveals complex nested morphological and kinematic features of molecular outf…
