Chemical abundance analysis of symbiotic giants. Metallicity and CNO abundance patterns in 14 northern S-type systems
Cezary Gałan, Joanna Mikołajewska, Kenneth H. Hinkle +1
In previous works, we computed abundances for the red giant in nearly four dozen S-type symbiotic systems (SySt). The abundances provide information about metallicity, evolutionary…
The Rapidly Evolving AGB Star, V Hya: ALMA finds a Multi-Ring Circus with High-Velocity Outflows
R. Sahai, P-S. Huang, S. Scibelli +3
We have observed the mass-losing carbon star V Hya that is apparently transitioning from an AGB star to a bipolar planetary nebula, at an unprecedented angular resolution of ~0".4-…
V4334 Sgr (Sakurai's Object): still churning out the dust
A. Evans, D. P. K. Banerjee, T. R. Geballe +5
We present a m spectrum of the Very Late Thermal Pulse object V4334 Sgr (Sakurai's Object), obtained in 2020 September. The spectrum displays a continuum that rises str…
The M Supergiant High Mass X-Ray Binary 4U 1954+31
K. H. Hinkle, T. Lebzelter, F. C. Fekel +5
The X-ray binary 4U 1954+31 has been classified as a Low Mass X-ray Binary (LMXB) containing a M giant and a neutron star (NS). It has also been included in the rare class of X-ray…
Carbon and Oxygen Isotopic Ratios. II. Semiregular Variable M Giants
Thomas Lebzelter, Kenneth H. Hinkle, Oscar Straniero +3
Carbon and oxygen isotopic ratios are reported for a sample of 51 SRb- and Lb-type variable asymptotic giant branch stars. Vibration-rotation first- and second-overtone CO lines in…
Precision Analysis of Evolved Stars
Stephen Ridgway, Rachel Akeson, Ellyn Baines +20
Evolved stars dominate galactic spectra, enrich the galactic medium, expand to change their planetary systems, eject winds of a complex nature, produce spectacular nebulae and illu…
