Constraints on the Radial Variation of Grain Growth in the AS 209 Circumstellar Disk

Laura M. Pérez, John M. Carpenter, Claire J. Chandler +18

We present dust continuum observations of the protoplanetary disk surrounding the pre-main sequence star AS 209, spanning more than an order of magnitude in wavelength from 0.88 to…

How ALMA is calibrated: I Antenna-based pointing, focus and amplitude calibration

T. van Kempen, S. Corder, R. Lucas +1

Here we will discuss which calibrations are needed, how to perform them and how the calibration affect ALMA observations. This first part concentrates on aspects related to a singl…

Kinematics of the CO Gas in the Inner Regions of the TW Hya Disk

Katherine A. Rosenfeld, Chunhua Qi, Sean M. Andrews +7

We present a detailed analysis of the spatially and spectrally resolved 12CO J=2-1 and J=3-2 emission lines from the TW Hya circumstellar disk, based on science verification data f…

The first ALMA view of IRAS 16293-2422: Direct detection of infall onto source B and high-resolution kinematics of source A

Jaime E. Pineda, Anaëlle J. Maury, Gary A. Fuller +9

Aims: We focus on the kinematical properties of a proto-binary to study the infall and rotation of gas towards its two protostellar components. Methods: We present ALMA Science Ver…

Constraining the Planetary System of Fomalhaut Using High-Resolution ALMA Observations

Aaron C. Boley, Matthew J. Payne, Stuartt Corder +3

The dynamical evolution of planetary systems leaves observable signatures in debris disks. Optical images trace micron-sized grains, which are strongly affected by stellar radiatio…

Observations of a high-mass protostar in NGC 7538S

Melvyn Wright, Jun-Hui Zhao, Goran Sandell +3

We present high angular resolution continuum observations of the high-mass protostar NGC 7538S with BIMA and CARMA at 3 and 1.4 mm, VLA observations at 1.3, 2, 3.5 and 6 cm, and ar…
