Journal ArticleDOI
Mass, linear momentum and kinetic energy of bipolar flows in protoplanetary nebulae
TL;DR: In this paper, the authors studied the CO emission from protoplanetary nebulae (PPNe) and identified a slowly expanding shell (represented in the spectra by a central core) and a fast outflow (corresponding to the line wings).
Journal ArticleDOI
The highly collimated bipolar outflow of OH 231.8+4.2 ?
TL;DR: In this article, high-resolution observations of CO molecular emission (J = 1 0a nd J = 2 1 lines) in the post-AGB bipolar nebula OH 231.8+4.2 are presented.
Journal ArticleDOI

TL;DR: In this paper, the spectral analysis of 31 Halpha-selected regions in the extended UV (XUV) disks of M83 (NGC5236) and NGC4625 recently discovered by GALEX was performed using IMACS at Las Campanas Observatory 6.5m Magellan I telescope and COSMIC at the Palomar 200-inch telescope.
Journal ArticleDOI

TL;DR: In this paper, the authors carried out a millimeter wavelength line survey between 79 and 356 GHz with the IRAM-30m telescope to investigate the physical and chemical properties of the molecular envelope of the oxygen-rich AGB star IK Tau.
Journal ArticleDOI
ALMA observations of the Red Rectangle, a preliminary analysis
Valentin Bujarrabal,A. Castro-Carrizo,Javier Alcolea,H. Van Winckel,C. Sánchez Contreras,Miguel Santander-García,Roberto Neri,R. Lucas +7 more
TL;DR: In this paper, the authors obtained high-quality ALMA observations of CO and CO J = 3−2 and COJ = 6−5 line emission in the Red Rectangle, the only post-AGB/protoplanetary object for which a disk in rotation has been mapped.
