The detection and simulation of a type Ia supernova with an early, red flash suggests that it formed through detonation of the helium shell of a white dwarf, rather than by collision of the ejecta ...

Observations of declining ultraviolet emission from a type Ia supernova within four days of the explosion are as expected if material ejected by the supernova collided with a companion star ...

Supernova SNLS-03D3bb is more than twice as bright as most Type Ia supernovae but has much less kinetic energy, and appears to be half again as massive as a typical Type Ia.

We’re essentially opening a new window on the transient universe” said Matthew Siebert of the Space Telescope Science Institute, capturing the awe that swept through the astrophysics community after ...

Supernova SNLS-03D3bb is more than twice as bright as most Type Ia supernovae but has much less kinetic energy, and appears to be half again as massive as a typical Type Ia.

Type Ia supernovae have revealed much about the nature of our universe — including the fact that not only is it expanding, but it is doing so faster now than in the past.

The Weirdest Type Ia Supernova Yet Date: September 25, 2006 Source: Lawrence Berkeley National Laboratory Summary: Scientists from the University of Toronto, Lawrence Berkeley National Laboratory ...

It was shortly confirmed as a type Ia supernova in the Pinwheel Galaxy, some 21 million light-years distant. That’s unusually close by cosmic standards, and the nearest SN Ia since 1986; ...

This tells us that Type Ia supernova are not caused by the core collapse of a star, but rather some kind of thermal runaway ...

Closest Type Ia supernova in decades solves a cosmic mystery Date: December 14, 2011 Source: DOE/Lawrence Berkeley National Laboratory Summary: Even as the "supernova of a generation" came into ...

That left the much rarer Type Ia supernova as the strongest candidate, events that generally occur once or twice each century in a given galaxy. These supernovas are the source of most of the iron ...
