The porous envelope and circumstellar wind matter of the closest carbon star, CW Leonis
Hyosun Kim, Ho-Gyu Lee, Youichi Ohyama +5
Recent abrupt changes of CW Leonis may indicate that we are witnessing the moment that the central carbon star is evolving off the Asymptotic Giant Branch (AGB) and entering into t…
Rubin Observatory LSST Transients and Variable Stars Roadmap
Kelly M. Hambleton, Federica B. Bianco, Rachel Street +79
The Vera C. Rubin Legacy Survey of Space and Time holds the potential to revolutionize time domain astrophysics, reaching completely unexplored areas of the Universe and mapping va…
Multi-epoch Optical Images of IRC+10216 Tell About the Central Star And the Adjacent Environment
Hyosun Kim, Ho-Gyu Lee, Youichi Ohyama +5
Six images of IRC+10216 taken by the Hubble Space Telescope at three epochs in 2001, 2011, and 2016 are compared in the rest frame of the central carbon star. An accurate astrometr…
A search for distant, pulsating red giants in the southern halo
Nicolas Mauron, Kamo S. Gigoyan, Tim R. Kendall +1
To investigate the asymptotic giant branch (AGB) population in the Galactic halo, we search for pulsating AGB stars at a heliocentric distance over 50kpc. Our research is based on…
A catalogue of oxygen-rich pulsating giants in the galactic halo and the Sagittarius stream
Nicolas Mauron, Luc P. A. Maurin, Tim R. Kendall
In order to construct a catalogue of oxygen-rich (noted M) asymptotic giant branch (AGB) stars in the halo, complementing those of carbon-rich (C) stars, previous lists of Miras an…
Investigation of long-period variables in the Catalina Southern catalog: new carbon stars and false objects
Nicolas Mauron, Kamo S. Gigoyan, Karen K. Gigoyan +2
As part of our ongoing study of the evolved giants in the galactic halo, we consider the sample of 1286 long-period variables (LPVs) in the southern hemisphere provided by the Cata…
