HI Observations of two New Dwarf Galaxies: Pisces A & B with the SKA Pathfinder KAT-7
C. Carignan, Y. Libert, D. M. Lucero +4
Context. Pisces A & Pisces B are the only two galaxies found via optical imaging and spectroscopy out of 22 HI clouds identified in the GALFAHI survey as dwarf galaxy candidates. A…
The multi-scale environment of RS Cnc from CO and HI observations
D. T. Hoai, L. D. Matthews, J. M. Winters +4
We present a detailed study of the circumstellar gas distribution and kinematics of the semi-regular variable star RS Cnc on spatial scales ranging from ~1" (~150 AU) to ~6' (~0.25…
Discovery of a detached HI gas shell surrounding alpha Orionis
T. Le Bertre, L. D. Matthews, E. Gérard +1
We report the detection of the HI line at 21 cm in the direction of alpha Ori with the Nancay Radiotelescope and with the Very Large Array. The observations confirm the previous de…
An HI 21-cm line survey of evolved stars
E. Gerard, T. Le Bertre, Y. Libert
The HI line at 21 cm is a tracer of circumstellar matter around AGB stars, and especially of the matter located at large distances (0.1-1 pc) from the central stars. It can give un…
HI Observations of the Asymptotic Giant Branch Star X Herculis: Discovery of an Extended Circumstellar Wake Superposed on a Compact High-Velocity Cloud
L. D. Matthews, Y. Libert, E. Gerard +3
We report HI 21-cm line observations of the AGB star X Her obtained with the Green Bank Telescope (GBT) and the Very Large Array (VLA). We have detected HI emission totaling M_HI=2…
HI and CO in the circumstellar environment of the S-type star RS Cnc
Yannick Libert, Jan Martin Winters, Thibaut Le Bertre +2
This paper presents interferometric and single-dish CO observations along with HI data obtained for the oxygen-rich semi-regular variable RS Cnc, in order to probe its circumstella…
