WebbDirect evidence of the latter was previously found only in two core-collapse supernova events, and appears to be absent in thermonuclear supernovae. Aims. We aim to to constrain the supernova progenitor types of Cassiopeia A, SN 1987A, Vela Jr., G1.9+0.3, SN1572, and SN1604 through their 44Ti ejecta masses and explosion kinematics. WebbNear-UV Hubble Space Telescope images of the remnant of SN 1885 (S And) in M31 show a 070±005 diameter absorption disk silhouetted against M31's central bulge, at SN 1885's historically reported position. The disk's size corresponds to a linear diameter of 2.5±0.4 pc at a distance of 725±70 kpc, implying an average expansion velocity of 11,000±2000 km …

WebbAs a result, these primordial AGB stars could have experienced a carbon deflagration, ending their lives as type I and 1/2 supernovae, i.e, thermonuclear supernovae, such as type Ia, but showing H in their spectra, such as type II. Later on, this scenario for metal-deficient AGB stars was substantially revised [11,17,25,26]. WebbAbstract. Supernovae of type Ia (SNe Ia) are very important for cosmography. To exclude systematic effects in linking the observed light of distant SNe Ia to the parameters of cosmological models, one has to understand the nature of supernova outbursts and to build accurate algorithms for predicting their emission.

The high mass stars (>8 M) responsible for type-II super-novae are short-lived and hence, the supernovae type-II rate declines very fast within a few tens of Myr period after a major episode of star formation. Therefore, the hostless type-II SN are extremely rare to detect. lake singletary sutton ma
