Type Ib supernovae are bluer than Type Ic supernovae
Astronomy & AstrophysicsType Ib and Ic supernovae (SNe Ib/Ic) are the bright finale of massive stars that have lost their hydrogen envelopes, making them powerful probes of mass stripping in massive star evolution.

Optical Color of Type Ib and Ic Supernovae and Implications for Their Progenitors [PDF]
The Astrophysical Journal, 2023 Type Ib and Ic supernovae (SNe Ib/Ic) originate from hydrogen-deficient massive star progenitors, of which the exact properties are still much debated.

SEARCHING FOR HYDROGEN IN TYPE Ib SUPERNOVAE [PDF]
The Astrophysical Journal, 2010 We present synthetic spectral fits of the typical Type Ib SN 1999dn and the Hydrogen Rich Ib SN 2000H using the generalized non-local thermodynamic equilibrium stellar atmospheres code \phx. We fit model spectra to five epochs of SN 1999dn ranging from ten days pre-maximum light to 17 days post-maximum light and the two earliest epochs of SN 2000H ...

Model Light Curves for Type Ib and Ic Supernovae [PDF]
, 2021 Using the Monte Carlo code SEDONA, multiband photometry and spectra are calculated for supernovae derived from stripped helium stars with presupernova masses of 2.2 to 10.0 M ⊙.

Progenitors of Type Ib Supernovae [PDF]
Symposium - International Astronomical Union, 1991 We argue that the progenitors of type Ib supernovae are moderately massive stars (M ~ 7 M⊙) in binary systems whereas the hypothesis that they originate from very massive stars (M > 20 M⊙) is not consistent with the observational evidence on SNIb.

Estimating Ejecta Masses of Stripped-envelope Supernovae Using Late-time Light Curves
The Astrophysical Journal, 2023 Stripped-envelope supernovae (SESNe) are a subclass of core-collapse supernovae that are deficient in hydrogen (SN IIb, SN Ib) and possibly helium (SN Ic) in their spectra.

Discovery of the Closest Ultra-stripped Supernova: SN 2021agco in UGC 3855
The Astrophysical Journal Letters, 2023 We present the discovery and studies of the helium-rich, fast-evolving supernova (SN) 2021agco at a distance of ∼40 Mpc. Its early-time flux is found to rise from half peak to the peak of −16.06 ± 0.42 mag in the r band within ${2.4}_{-1.0}^{+1.5}$ days,

The exceptionally bright Type Ib supernova 1991D [PDF]
Monthly Notices of the Royal Astronomical Society, 2002 Photometric and spectroscopic observations of the peculiar Type Ib Supernova 1991D are presented. SN 1991D was exceptionally bright for a Type Ib supernova. The He I lines were rather weak and the velocity at the photosphere as a function of time was unusually low.

The Iron Yield of Core-collapse Supernovae
The Astrophysical Journal, 2023 We present a systematic analysis of 191 stripped-envelope supernovae (SE SNe), aimed at computing their ^56 Ni masses from the luminosity in their radioactive tails ( ${M}_{\mathrm{Ni}}^{\mathrm{tail}}$ ) and/or in their maximum light, and the mean ^56 ...
