... Academy of Sciences, have developed a new model which explains the formation of the most youthful type Ia supernovae. In a paper published in Monthly Notices of the Royal Astronomical Society, Dr. Bo ...
... robotic telescopes and other supernova searches. Such searches have been looking primarily for Type Ia supernovae that could help astronomers understand the accelerating expansion of the universe, ...
... the history of astronomy, Tycho Brahe's supernova of 1572 (SN 1572), first identified more than 400 years ago, is a normal type Ia supernova, according to research published in the current (4 ...
Astronomers have developed a new model which explains the formation of the most youthful type Ia supernovae. They show how the transfer of material from a 'helium star' to a compact white dwarf ...
... -energy X-rays, respectively. Reynolds says that this pattern is best explained by a type Ia supernova, and that the difference in brightness corresponds to the level of synchrotronic X-rays present. ...
... star called a white dwarf) and a type Ia supernova (the destructive death of a white dwarf ... Hawaii, and NASA's Swift satellite.
In typical supernova explosions, light from different chemical elements ...
... disruption of a white dwarf, known as a Type Ia supernova, or the collapse of an iron core and rebound ... 2002bj dropped off so rapidly that the supernova disappeared 20 days after its discovery. An image ...
Stellar explosions known as type Ia supernovae have proved invaluable to astrophysicists as markers of cosmic distance. ... the sky. Just a decade ago type Ia supernovae took center stage when researchers ...
Cosmologists call for decades-long survey of type-Ia supernovae
... Project based at Berkeley Lab, comparing the brightness and redshift of distant Type Ia supernovae. The results showed that the expansion of the universe was accelerating, driven by something which, ...
... has proven difficult.
In 1998, studies of distant explosions called "type Ia supernovae" indicated that the expansion of the Universe is accelerating, an observation attributed to the repulsive ...
... Yale University, have found a new technique that establishes the intrinsic brightness of Type Ia supernovae more accurately than ever before. These exploding stars are the best standard candles for ...
... -dwarf star that disintegrated in a thermonuclear explosion, known as a Type Ia supernova, but it does not look like other likely Type Ia remnants found in our own Milky Way galaxy.
... models of dark energy, however, exquisite spectrometry of thousands of distant Type Ia supernovae will be needed. This can only be done by flying a big telescope and an adequate spectrograph in space ...
... a neutron star. The explosion of a white dwarf is the leading explanation for 'type Ia supernovae', bright events that are used as standard beacons by astronomers to measure the expansion of the ...
