X-Ray Emission from Planetary Nebulae Calculated by 1D Spherical Numerical Simulations
Muhammad Akashi, Noam Soker, Ehud Behar +1
We calculate the X-ray emission from both constant and time evolving shocked fast winds blown by the central stars of planetary nebulae (PNs) and compare with observations. Using s…
Hubble Space Telescope Ultraviolet Spectroscopy of Fourteen Low-Redshift Quasars
Rajib Ganguly, Michael S. Brotherton, Nahum Arav +35
We present low-resolution ultraviolet spectra of 14 low redshift (z<0.8) quasars observed with HST/STIS as part of a Snap project to understand the relationship between quasar outf…
High-resolution X-ray Spectroscopy of BD +30 3639
Joel H. Kastner, Young Sam Yu, John Houck +3
We present preliminary results from the first X-ray gratings spectrometer observations of a planetary nebula (PN). We have used the Chandra X-ray Observatory Low Energy Transmissio…
A hot transient outflow from eta Carinae
Ehud Behar, Raanan Nordon, Eyal Ben-Bassat +1
eta Carinae is a stellar binary system with a period of 5.54 years. It harbors one of the brightest and most massive stars in our galaxy. This paper presents spectroscopic evidence…
Accretion onto the Companion of Eta Carinae During the Spectroscopic Event: III. the He II 4686 Line
Noam Soker, Ehud Behar
We continue to explore the accretion model of the massive binary system eta Carinae by studying the anomalously high He II 4686 line. The line appears just before periastron and di…
