A second post-AGB nebula that contains gas in rotation and in expansion: ALMA maps of IW Car
V. Bujarrabal, A. Castro-Carrizo, H. Van Winckel +2
We aim to study the presence of both rotation and expansion in post-AGB nebulae, in particular around IW Car, a binary post-AGB star that was suspected to be surrounded by a Kepler…
ALMA Compact Array observations of the Fried Egg nebula: Evidence for large-scale asymmetric mass-loss from the yellow hypergiant IRAS 17163-3907
Sofia Wallstrom, E. Lagadec, S. Muller +12
Yellow hypergiants are rare and represent a fast evolutionary stage of massive evolved stars. That evolutionary phase is characterised by a very intense mass loss, the understandin…
Probing seismic solar analogues through observations with the NASA Kepler space telescope and HERMES high-resolution spectrograph
P. G. Beck, D. Salabert, R. A. García +21
Stars similar to the Sun, known as solar analogues, provide an excellent opportunity to study the preceding and following evolutionary phases of our host star. The unprecedented qu…
The discovery of a planetary candidate around the evolved low-mass Kepler giant star HD 175370
M. Hrudková, A. Hatzes, R. Karjalainen +20
We report on the discovery of a planetary companion candidate with a minimum mass Msini = 4.6 M_J orbiting the K2 III giant star HD 175370 (KIC 007940959). This star was a target i…
Noise optimization of the source follower of a CMOS pixel using BSIM3 noise model
Swaraj Mahato, Guy Meynants, Gert Raskin +2
CMOS imagers are becoming increasingly popular in astronomy. A very low noise level is required to observe extremely faint targets and to get high-precision flux measurements. Alth…
Further ALMA observations and detailed modeling of the Red Rectangle
V. Bujarrabal, A. Castro-Carrizo, J. Alcolea +3
We present new high-quality ALMA observations of the Red Rectangle (a well known post-AGB object) in C17O J=6-5 and H13CN J=4-3 line emission and results from a new reduction of al…
