After comparing it with similar curves, such as that of Kepler's Supernova
of 1604, he categorized SN 1572 as a Type I object that showed a linear decrease in brightness.
Astronomers have used a very long Chandra observation of the remnant of Kepler's supernova
to deduce that the supernova was triggered by an interaction between a white dwarf and a red giant star.
is one of the most recent type Ia explosions known in our galaxy, so it represents an essential link to improving our knowledge of these events," said Carles Badenes, an assistant professor of physics and astronomy at the University of Pittsburgh.
As a result of this work, SN1604 is now also known as Kepler's Supernova
A nova in 1572 was recorded by Danish astronomer Tycho Brahe and another appeared in 1604, known as Kepler's Supernova
. But there are no similarly concrete charts of the royal star.
It was the exploding star now known as Kepler's supernova
, the last one that astronomers have witnessed in the Milky Way (SN: 12/11/04, p.
The proceedings of the international conference, which took place in Padua on 16-19 June 2004 to commemorate the 400th anniversary of the appearance of Kepler's Supernova
, are collected in this publication.
The last supernova seen in our own Milky Way was "Kepler's Supernova
" of 1604 (June issue, page 28).
Although the 1604 eruption, now known as Kepler's supernova
, incinerated within seconds, the shock wave from the blast endures.
For example, the observations of the remnant of Kepler's supernova
in 1604 and the recent supernova PTF 11kx have shown evidence that the companion star is a red giant.
The new observations firmly place Kepler's supernova
in the Type Ia category.
CHRISTMAS AND KEPLER'S SUPERNOVA
. Exactly 400 years ago this fall, a new star shining at magnitude -3 appeared in Ophiuchus low in the southwestern twilight.
