Coevality in Young Eclipsing Binaries
M. Simon, J. Toraskar
The ages of the components in very short period pre-main sequence (PMS) binaries are essential to an understanding of their formation. We considered a sample of 7 PMS eclipsing bin…
HST Images Flash Ionization of Old Ejecta by the 2011 Eruption of Recurrent Nova T Pyxidis
Michael M. Shara, David Zurek, Bradley E. Schaefer +8
T Pyxidis is the only recurrent nova surrounded by knots of material ejected in previous outbursts. Following the eruption that began on 2011 April 14.29, we obtained seven epochs…
Dynamical Fragmentation of the T Pyxidis Nova Shell During Recurrent Eruptions
Jayashree Toraskar, Mordecai-Mark Mac Low, Michael M. Shara +1
Hubble Space Telescope} images of the ejecta surrounding the nova T Pyxidis resolve the emission into more than two thousand bright knots. We simulate the dynamical evolution of th…
Dynamical Expansion of H II Regions from Ultracompact to Compact Sizes in Turbulent, Self-Gravitating Molecular Clouds
Mordecai-Mark Mac Low, Jayashree Toraskar, Jeffrey S. Oishi +1
The nature of ultracompact H II regions (UCHRs) remains poorly determined. In particular, they are about an order of magnitude more common than would be expected if they formed aro…
