Binarity in Cool Asymptotic Giant Branch Stars: A Galex Search for Ultraviolet Excesse
R. Sahai, K. Findeisen, A. Gil de Paz +1
The search for binarity in AGB stars is of critical importance for our understanding of how planetary nebulae acquire the dazzling variety of aspherical shapes which characterises…

Echelle long-slit optical spectroscopy of evolved stars
C. Sanchez Contreras, R. Sahai, A. Gil de Paz +1
We present echelle long-slit optical spectra of a sample of objects evolving off the AGB, most of them in the pre-planetary nebula (pPN) phase, obtained with the ESI and MIKE spect…

A Massive Bipolar Outflow and a Dusty Torus with Large Grains in the Pre-Planetary Nebula IRAS 22036+5306
R. Sahai, K. Young, N. A. Patel +2
We report high angular-resolution (~1") CO J=3--2 interferometric mapping, using the Submillimeter Array (SMA), of IRAS22036+5306 (I22036), a bipolar pre-planetary nebula (PPN) wit…
