The Molecular Circumstellar Environments of Red Supergiants in Galactic Open Clusters
Mark A. Siebert, Elvire De Beck, Guillermo Quintana-Lacaci +4
We aim to expand the sample of RSGs with direct measurements of circumstellar gas through millimeter observations of two of the largest coeval RSG populations in the Galaxy: the op…
HST observations of chromospheric UV lines in the AGB star R Leo
Maryam Saberi, Donald G. Luttermoser, Graham M. Harper +3
The role of stellar chromospheres in the chemistry, mass loss, and evolution of cool evolved stars remains poorly understood. We present high-resolution ultraviolet spectra of the…
Probing sulfur chemistry in oxygen-rich AGB stars with ALMA
Prasanta Gorai, Maryam Saberi, Theo Khouri +1
Sulfur and its isotopic ratios play a crucial role in understanding astrophysical environments, providing insights into nucleosynthesis, ISM processes, star formation, planetary ev…
The SOFIA Massive (SOMA) Star Formation Q-band Follow-up. II. Hydrogen Recombination Lines Toward High-Mass Protostars
Prasanta Gorai, Kotomi Taniguchi, Jonathan C. Tan +11
Hydrogen recombination lines (HRLs) are valuable diagnostics of the physical conditions in ionized regions around high-mass stars. Understanding their broadening mechanisms and int…
Detection of CI line emission towards the oxygen-rich AGB star omi Cet
M. Saberi, W. H. T. Vlemmings, E. De Beck +2
We present the detection of neutral atomic carbon CI(3 P1 - 3 P0 ) line emission towards omi Cet. This is the first time that CI is detected in the envelope around an oxygen-rich M…
