Molecular Distributions and Abundances in the Binary-Shaped Outflow of V Hya
Mark A. Siebert, Raghvendra Sahai, Samantha Scibelli +1
Binaries are known to play a key role in the mass loss and dynamical environments of evolved stars. Stellar and sub-stellar companion interactions produce complex wind morphologies…
A Survey of Deuterated Ammonia in the Cepheus Star-Forming Region L1251
Maria Galloway-Sprietsma, Yancy L. Shirley, James Di Francesco +4
Understanding the chemical processes during starless core and prestellar core evolution is an important step in understanding the initial stages of star and disk formation. This pr…
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-…
High-Velocity Bullets from V Hydrae, an AGB Star in Transition: Ejection History and Spatio-Kinematic Modeling
Samantha Scibelli, Raghvendra Sahai, Mark Morris
The carbon star V Hydrae (V Hya) provides new insight into the nature of the launching mechanism of jet-like outflows that are believed to be the cause of the poorly understood tra…
High-Speed Bullet Ejections during the AGB to Planetary Nebula Transition: HST Observations of the Carbon Star, V Hydrae
R. Sahai, S. Scibelli, M. R. Morris
The well-studied carbon star, V Hya, showing evidence for high-speed, collimated outflows and dense equatorial structures, is a key object in the study of the poorly understood tra…
