New Insights into an Old Nova
Today’s authors use the integral field spectroscopy observations to get new insights of the old RR Pictoris Nova.
No Nova Neutrinos?
Today’s authors investigate why neutrino detectors have yet to observe neutrinos from novae!
A Historical Nova and the First Radioactive Molecule in Space
An explosive stellar merger reveals the first radioactive molecule discovered in space.
Signals from Hidden Dwarf Galaxies
There is quite a lot left to learn about the smallest galaxies in our Universe, dwarf galaxies. Since they are small compared to galaxies like the Milky Way, they are challenging to observe directly, either because they are too dim or because they are too small to be resolved. The authors suggest a new detection method for these faint galaxies that takes advantage of ongoing and upcoming large surveys looking for, among other things, novae and supernovae.
Morpho-Kinematics of a Galactic Nova
Novae are thermonuclear explosions that occur on the surface of a white dwarf following the accretion of matter from a nearby companion star. The authors seek to understand the geometry and velocity of the ejected material.
Two stars merged, and we got to watch
V1309 Sco first caught astronomers attention in 2008, when it displayed an outburst, suddenly getting a hundred times brighter. Due its location near the Galactic center, V1309 Sco has been monitored by the OGLE, which is looking for microlensing events, since 2001. The authors of this paper were able to look back into this archive of data and see what V1309 Sco was doing before it erupted.
