Unprecedented nova images illuminate astronomers' models for its ejecta
astronomy image fireball stage
2014/10/30
The first images of a nova during its early fireball stage--when it ejects material, and gases expand and cool--show that this activity is more complicated than predicted.
Highly-detailed radio-telescope images have pinpointed the locations where a stellar explosion called a nova emitted gamma rays, the most energetic form of electromagnetic waves. The discovery reveale...
Scientists on the world's longest-distance neutrino experiment announced today that they have seen their first neutrinos.
The Orbital Period and Variability of the Dwarf Nova ES Draconis
stars: individual: ES Dra (PG 1524+622) – novae: cataclysmic variables – binaries: spectroscopic – AAVSO
2011/10/12
A radial velocity study of the cataclysmic variable ES Dra (PG 1524+622) is presented. ES Dra is found to have an orbital period of 0.17660 \pm 0.00006 d (4.2384 \pm 0.0014 h). The mass-losing seconda...

We present radio light curves and spectra of the classical nova V1723 Aql obtained with the Expanded Very Large Array (EVLA). This is the first paper to showcase results from the EVLA Nova Project, wh...
Quark nova imprint in the extreme supernova explosion SN 2006gy: the advent of the Quark Star
Quark nova imprint the extreme supernova explosion SN 2006gy
2011/1/11
The existence of quark stars has until now been purely hypothetical. In this work, we uncover undeniable evidence of these exotic objects with far reaching implications to various branches of physics ...

We present the 2005–2010 outburst history of the SUUMa-type dwarf HS 0417+7445,along with a detailed analysis of extensive time-series photometry obtained in March 2008 during the second recorded supe...
The 2010 nova outburst of the symbiotic Mira V407 Cyg
Stars novae – Stars symbiotic stars – Miras
2010/11/10
The nova outburst experienced in 2010 by the symbiotic binary Mira V407 Cyg has been extensively studied at optical and infrared wavelengths with both photometric and spectroscopic observations. This ...
Quark-Nova Explosion inside a Collapsar：Application to Gamma Ray Bursts
Quark-Nova Explosion Collapsar Gamma Ray Bursts
2009/9/4
If a quark-nova occurs inside a collapsar, the interaction between the quark-nova ejecta (relativistic iron-rich chunks) and the collapsar envelope leads to features indicative of those observed in Ga...
