WebType Ib supernovaeare rare explosions where the progenitor star lacks an outer layer of hydrogen.It has proven difficult to pin down which kinds of stars give rise to these supernovae. One of the most promising ideas is that they originate fromWolf-Rayet stars.. These stars are about ten times more massive and thousands of times brighter than the … WebCurrent time domain facilities are finding several hundreds of transient astronomical events a year. The discovery rate is expected to increase in the future as soon as new surveys such as the Zwicky Transient Facility (ZTF) and the Large Synoptic Sky Survey (LSST) come on line. At the present time, the rate at which transients are classified is approximately one … WebPDF - We present the analysis of the first Nuclear Spectroscopic Telescope Array observations (~220 ks), simultaneous with the last Suzaku observations (~50 ks), of the active galactic nucleus of the bright Seyfert 1 galaxy Mrk 509. The time-averaged spectrum in the 1–79 keV X-ray band is dominated by a power-law continuum (Γ ~ 1.8–1.9), a … how do you spell shotty
