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…
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…
Installation of the Dark Energy Spectroscopic Instrument at the Mayall 4-meter telescope
Robert Besuner, Lori Allen, Charles Baltay +34
The Dark Energy Spectroscopic Instrument (DESI) is a Stage IV ground-based dark energy experiment that will measure the expansion history of the Universe using the Baryon Acoustic…
Performance of Kitt Peak's Mayall 4-meter Telescope During DESI Commissioning
Aaron M. Meisner, Behzad Abareshi, Arjun Dey +21
In preparation for the Dark Energy Spectroscopic Instrument (DESI), a new top end was installed on the Mayall 4-meter telescope at Kitt Peak National Observatory. The refurbished t…
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…
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…
