Testing particle trapping in transition disks with ALMA
P. Pinilla, N. van der Marel, L. M. Pérez +6
We present new Atacama Large Millimeter/submillimeter Array (ALMA) continuum observations at 336GHz of two transition disks, SR21 and HD135344B. In combination with previous ALMA o…
A concentration of centimeter-sized grains in the Oph IRS 48 dust trap
Nienke van der Marel, Paola Pinilla, John Tobin +4
Azimuthally asymmetric dust distributions observed with ALMA in transition disks have been interpreted as dust traps. We present VLA Ka band (34 GHz or 0.9 cm) and ALMA Cycle 2 Ban…
A Combined Spitzer and Herschel Infrared Study of Gas and Dust in the Circumbinary Disk Orbiting V4046 Sgr
Valerie A. Rapson, Benjamin Sargent, G. Germano Sacco +6
We present results from a spectroscopic Spitzer and Herschel mid-to-far-infrared study of the circumbinary disk orbiting the evolved (age ~12-23 Myr) close binary T Tauri system V4…
Outflow forces in intermediate mass star formation
T. A. van Kempen, M. R. Hogerheijde, E. F. van Dishoeck +22
Intermediate mass protostarsprovide a bridge between theories of low- and high-mass star formation. Emerging molecular outflows can be used to determine the influence of fragmentat…
APEX-CHAMP+ high-J CO observations of low-mass young stellar objects: IV. Mechanical and radiative feedback
Umut A. Yıldız, Lars E. Kristensen, Ewine F. van Dishoeck +14
During the embedded stage of star formation, bipolar molecular outflows and UV radiation from the protostar are important feedback processes. Our aim is to quantify the feedback, m…
