Revisiting the extremely long-period cataclysmic variables V479 Andromedae and V1082 Sagitarii
Gagik Tovmassian, Diogo Belloni, Anna F. Pala +56
The overwhelming majority of CVs have orbital periods shorter than 10 hr. However, a few have much longer periods, and their formation and existence pose challenges for the CV evol…
On the Domination Number of Permutation Graphs and an Application to Strong Fixed Points
Theresa Baren, Michael Cory, Mia Friedberg +6
A permutation graph is a simple graph with vertices corresponding to the elements of and an edge between and when and are inverted in . A set of vertic…
Three X-ray Flares Near Primary Eclipse of the RS CVn Binary XY UMa
Hang Gong, Rachel Osten, Thomas Maccarone +3
We report on an archival X-ray observation of the eclipsing RS CVn binary XY UMa ( 0.48d). In two ACIS observations spanning 200 ks and almost…
Ice Melt, Sea Level Rise and Superstorms: Evidence from Paleoclimate Data, Climate Modeling, and Modern Observations that 2°C Global Warming is Dangerous
James Hansen, Makiko Sato, Paul Hearty +16
We use numerical climate simulations, paleoclimate data, and modern observations to study the effect of growing ice melt from Antarctica and Greenland. Meltwater tends to stabilize…
Negative Refraction Does Not Make Perfect Lenses
Weiguo Yang, Michael A. Fiddy
The widely-accepted theoretical treatment of the electromagnetic boundary problem of evanescent wave transfer at an interface between a normal medium of n=1 and an ideal negative i…
Analytical Approximation of the Neutrino Oscillation Matter Effects at large
Sanjib Kumar Agarwalla, Yee Kao, Tatsu Takeuchi
We argue that the neutrino oscillation probabilities in matter are best understood by allowing the mixing angles and mass-squared differences in the standard parametrization to `ru…
