Spatially-resolved stellar population properties of the M51-NGC 5195 system from multi-wavelength photometric data
Kong, Xu; Zou, Hu; Lin, Lin +5 more
Using multi-band photometric images of M51 and its companion NGC 5195 from ultraviolet to optical and infrared, we investigate spatially resolved stellar population properties of this interacting system with stellar population synthesis models. The observed infrared excess (IRX) is used to constrain dust extinction. Stellar mass is also inferred f…
Symmetry properties and widths of the filamentary structures in the Orion A giant molecular cloud
Zheng, Yu-Qing; Wang, Hong-Chi; Ma, Yue-Hui +1 more
We identify 225 filaments from an H2 column density map constructed using simultaneous 12CO, 13CO and C18O (J = 1-0) observations carried out as a part of the Milky Way Imaging Scroll Painting (MWISP) project.We select 46 long filaments with lengths above 1.2 pc to analyze the filament column density pro…
Ice lines as the origin for the gap/ring structure in protoplanetary disks: the issue of the assumed temperature profile
Liu, Yao
Gaps and rings are commonly seen in recent high-resolution ALMA observations of protoplanetary disks. Ice lines of volatiles are one of the mechanisms proposed to explain the origin for these substructures. To examine the ice line hypothesis, literature studies usually parameterize the mid-plane temperature with the analytic formula of a passively…
