A carbon-rich hot bubble in the planetary nebula NGC 5189
J. A. Toalá, R. Montez, M. Karovska
We present the discovery of extended X-ray emission from the planetary nebula (PN) NGC 5189 around the [WO1]-type WD 1330-657 with XMM-Newton. The X-ray-emitting gas fills the cavi…
A Chandra Study: Are Dwarf Carbon Stars Spun Up and Rejuvenated by Mass Transfer?
Paul J. Green, Rodolfo Montez, Fernando Mazzoni +9
Carbon stars (with C/O> 1) were long assumed to all be giants, because only AGB stars dredge up significant carbon into their atmospheres. The case is nearly iron-clad now that the…
Planetary Nebulae and How to Find Them: Color Identification in Big Broadband Surveys
George Vejar, Rodolfo Montez, Margaret Morris +1
Planetary nebulae (PNe) provide tests of stellar evolution, can serve as tracers of chemical evolution in the Milky Way and other galaxies, and are also used as a calibrator of the…
A New Radio Molecular Line Survey of Planetary Nebulae: HNC/HCN as a Diagnostic of Ultraviolet Irradiation
Jesse Bublitz, Joel H. Kastner, Miguel Santander-García +3
Certain planetary nebulae contain shells, filaments, or globules of cold gas and dust whose heating and chemistry are likely driven by UV and X-ray emission from their central star…
Cool, evolved stars: results, challenges, and promises for the next decade
Gioia Rau, Rodolfo Montez, Kenneth G. Carpenter +27
Cool, evolved stars are the main source of chemical enrichment of the interstellar medium (ISM), and understanding their mass loss and structure offers a unique opportunity to stud…
