Silicon isotopic abundance toward evolved stars and its application for presolar grains
T. -C. Peng, E. M. L. Humphreys, L. Testi +8
Galactic chemical evolution (GCE) is important for understanding the composition of the present-day interstellar medium (ISM) and of our solar system. In this paper, we aim to trac…
High-Angular-Resolution and High-Sensitivity Science Enabled by Beamformed ALMA
Vincent Fish, Walter Alef, James Anderson +66
An international consortium is presently constructing a beamformer for the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile that will be available as a facility instrum…
A synchrotron jet from a post-AGB star
A. F. Pérez-Sánchez, W. H. T. Vlemmings, D. Tafoya +1
(Abridged) The evolution of low- and intermediate-initial-mass stars beyond the asymptotic giant branch (AGB) remains poorly understood. High-velocity outflows launched shortly aft…
ALMA Observations of the Coldest Place in the Universe: The Boomerang Nebula
R. Sahai, W. H. T. Vlemmings, P. J. Huggins +2
The Boomerang Nebula is the coldest known object in the Universe, and an extreme member of the class of Pre-Planetary Nebulae, objects which represent a short-lived transitional ph…
ALMA observations of the variable 12CO/13CO ratio around the asymptotic giant branch star R Sculptoris
W. H. T. Vlemmings, M. Maercker, M. Lindqvist +7
[abridged] The 12CO/13CO ratio is often used as a measure of the 12C/13C ratio in the circumstellar environment, carrying important information about the stellar nucleosynthesis. E…
EVN observations of 6.7-GHz methanol maser polarization in massive star-forming regions II. First statistical results
G. Surcis, W. H. T. Vlemmings, H. J. van Langevelde +2
Magnetic fields have only recently been included in theoretical simulations of high-mass star formation. The simulations show that magnetic fields play an important role in the for…
