Self-gravitating filament formation from shocked flows: velocity gradients across filaments

Autor: Che-Yu Chen, S. Storm, Eve C. Ostriker, A. Dhabal, Lee G. Mundy

Publikováno v: Monthly Notices of the Royal Astronomical Society. 494:3675-3685

In typical environments of star-forming clouds, converging supersonic turbulence generates shock-compressed regions, and can create strongly-magnetized sheet-like layers. Numerical MHD simulations show that within these post-shock layers, dense filam

Four annular structures in a protostellar disk less than 500,000 years old

Autor: Dominique M, Segura-Cox, Anika, Schmiedeke, Jaime E, Pineda, Ian W, Stephens, Manuel, Fernández-López, Leslie W, Looney, Paola, Caselli, Zhi-Yun, Li, Lee G, Mundy, Woojin, Kwon, Robert J, Harris

Publikováno v: Nature. 586(7828)

Annular structures (rings and gaps) in disks around pre-main-sequence stars have been detected in abundance towards class II protostellar objects that are approximately 1,000,000 years old

Annular structures, or rings and gaps, in disks around pre-main sequence stars have been detected in abundance towards Class II objects ~1,000,000 years in age. These structures are often interpreted as evidence of planet formation, with planet-mass

Connecting the Scales: Large Area High-resolution Ammonia Mapping of NGC 1333

Autor: Shaye Storm, Lee G. Mundy, Arnab Dhabal, Peter Teuben, Che-Yu Chen

We use NH3 inversion transitions to trace the dense gas in the NGC 1333 region of the Perseus molecular cloud. NH3(1,1) and NH3(2,2) maps covering an area of 102 square arcminutes at an angular resolution of ~3.7" are produced by combining VLA interf

Publikováno v: Optical and Infrared Interferometry and Imaging VI.

BETTII (Balloon Experimental Twin Telescope for Infra-red Interferometry) is designed to provide high angular resolution spectroscopic data in the far-infrared (FIR) wavelengths. The most significant limitation for BETTII is its sensitivity; obtainin
