SN 19841 - Another type Ib supernova
Publications of the Astronomical Society of the Pacific, 1990This object was discovered ~ 15 days before maximum light and was observed photometrically over a period of five weeks. A spectrum obtained near maximum shows that this supernova was a relatively distant Type-Ib event. Like other Type-Ib supernovae, 1984I was characterized by a red (B - V) color and low absolute magnitude at maximum.

In this chapter presents supernovae of Type Ib (SN Ib), the distinguishing characteristic of which is presence of helium spectral lines in optical spectra. Hydrogen lines are absent or inconspicuous, indicating that most or all of the hydrogen envelope was lost prior to explosion.

The X-ray Emission of Type Ib∕c Supernovae
AIP Conference Proceedings, 2007Before the launch of Chandra and XMM‐Newton, only two type Ib/c supernovae had been observed in X‐rays (1994I and 1998bw). I will review briefly the advances of the past seven years in the early (days to weeks) X‐ray detection of type Ib/c supernovae, a recent effort to characterize the X‐ray emission of years‐old Ib/c supernovae (e.g., 2001em, 2003bg,

Type Ib Supernovae Wolf-Rayet Stars
1991Since Type Ib supernovae were identified as a class several years ago, the idea that their progenitors are massive stars that have lost their hydrogen envelopes has been quite popular. ENSMAN and WOOSLEY [1] calculated a series of numerical models to test this idea and found that, if SNIb do come from massive stars (as opposed to, say, white dwarfs ...

On the Nature of Type Ib Supernova Progenitors
1991The realization that there is a separate subclass of Type I supernovae (SNe) to be denoted as Type Ib came after the detailed study of the SN 1983N in M83 (PANAGIA et al [1]; see also PANAGIA [2], WHEELER and LEVREAULT [3], UOMOTO and KIRSHNER [4]). It was immediately clear that SN 1983N is distinctly different from the classical variety of Type I SNe (

Type Ib and Ic Supernovae: Models and Spectra
1997For the theorist, Type Ib and Ic supernovae are the explosion of massive stars that have lost their hydrogen envelopes. For the observer, Type Ib supernovae are those that show no evidence of hydrogen, a weak or absent Si II absorption feature near 6150 A at peak light, and strong oxygen emission at late times.

Type IB-IC Supernovae: Time Clocks of Seyfert Galaxies?
2002Type Ib-c supernovae appear to be more frequent with respect to type II supernovae in Seyfert than in normal galaxies by a factor ≈ 3. We suggest that this statistically significant difference may be the signature of young star formation in Seyferts, with average age τ ≤ 20 Myr.
