Optical and X-ray Correlations During the 2015 Outburst of the Black Hole V404 Cyg

Autor: Hynes, R. I., Robinson, E. L., Terndrup, D. M., Gandhi, P., Froning, C. S., Starrfield, R. M. Wagner S., Dhillon, V. S., Marsh, T. R.

We present a serendipitous multiwavelength campaign of optical photometry simultaneous with Integral X-ray monitoring of the 2015 outburst of the black hole V404 Cyg. Large amplitude optical variability is generally correlated with X-rays, with lags

We report on studies of classical nova (CN) explosions where we follow the evolution of thermonuclear runaways (TNRs) on oxygen–neon (ONe) white dwarfs (WDs). Using NOVA, a 1D hydrodynamic computer code, we accrete solar matter until the TNR is ong
