Paper Spotlight: “Determinations of the 12C/13C Ratio for the Secondary Stars of AE Aquarii, SS Cygni, and RU Pegasi”

A Type Ia supernova is the complete explosion of a white dwarf that was being orbited by a secondary star prior to the explosion. Their high luminosity allows them to be used as the primary cosmological distance indicator, yet their progenitors remain unknown. It is almost certain that the progenitors of Type Ia supernovae are…

Paper Spotlight: “A massive, dead disk galaxy in the early Universe”

NMSU Astronomy professor Dr. Moire Prescott recently co-authored an article in Nature on the surprising discovery of a massive, fast-spinning, disk-shaped galaxy in the early Universe that appears to be “dead”, in that it has long since stopped making any new stars.  Dr. Prescott contributed the dynamical modeling demonstrating that the galaxy is rotating more…

Paper Spotlight: “HALOGAS Observations of NGC 4559: Anomalous and Extra-planar HI and its Relation to Star Formation”

Carlos Vargas, a 5th year graduate student working with his adviser, Rene Walterbos, recently published a paper entitled “HALOGAS Observations of NGC 4559: Anomalous and Extra-planar HI and its Relation to Star Formation.” For this study, Carlos and the other authors analyzed new observations made by HALOGAS, a survey dedicated to analyzing interactions between spiral…

Paper Spotlight: “A Possible Mechanism for Driving Oscillations in Hot Giant Planets”

In the same way earthquakes can shake the Earth when tectonic plates shift, so too can stars shake, or more scientifically, oscillate, as a result of the motion of hot plasma inside of the star. Similarly, gas giant planets like Jupiter and Saturn can oscillate, too, but astronomers aren’t exactly sure as to why. Recently,…
