Modeling the Far-Infrared Polarization Spectrum of a High-Mass Star Forming Cloud

Dennis Lee, Che-Yu Chen, Giles Novak +7

The polarization spectrum, or wavelength dependence of the polarization fraction, of interstellar dust emission provides important insights into the grain alignment mechanism of in…

Dynamics in Star-forming Cores (DiSCo): Project Overview and the First Look toward the B1 and NGC 1333 Regions in Perseus

Che-Yu Chen, Rachel Friesen, Jialu Li +13

The internal velocity structure within dense gaseous cores plays a crucial role in providing the initial conditions for star formation in molecular clouds. However, the kinematic p…

Modeling CN Zeeman Effect Observations of the Envelopes of a Low-Mass Protostellar Disk and a Massive Protostar

Renato Mazzei, Zhi-Yun Li, Che-Yu Chen +3

We use the POLARIS radiative transfer code to produce simulated circular polarization Zeeman emission maps of the CN molecular line transition for two types of protoste…

Relative Alignment Between Magnetic Fields and Molecular Gas Structure in Molecular Clouds

Renato Mazzei, Zhi-Yun Li, Che-Yu Chen +3

We compare the structure of synthetic dust polarization with synthetic molecular line emission from radiative transfer calculations using a 3-dimensional, turbulent collapsing-clou…

Revealing the drag instability in one-fluid nonideal MHD simulations of a 1D isothermal C-shock

Pin-Gao Gu, Che-Yu Chen, Emma Shen +2

C-type shocks are believed to be ubiquitous in turbulent molecular clouds thanks to ambipolar diffusion. We investigate whether the drag instability in 1D isothermal C-shocks, infe…

The Davis-Chandrasekhar-Fermi Method Revisited

Che-Yu Chen, Zhi-Yun Li, Renato R. Mazzei +5

Despite the rich observational results on interstellar magnetic fields in star-forming regions, it is still unclear how dynamically significant the magnetic fields are at varying p…
