  1. 375. Stripped core collapse supernovae
    Dr Maryam Modjaz (Columbia University)

    Stripped-envelope core-collapse supernovae (i.e., SNe of Type IIb, Ib, Ic and broad-lined Ic) are supernovae whose massive progenitors have been stripped of progressively larger amounts of their hydrogen and helium envelopes. While the SNe Ic-bl associated with long Gamma Ray Bursts (GRBs) have been studied in detail, the full range of properties of normal or broad-lined SNe is not...

  2. 362. Carnegie Supernova Project Observations of Stripped Core-Collapse Supernovae
    Mrs Maximilian Stritzinger (Stockholm University)

    The Carnegie Supernova Project obtained detailed optical (uBgVri) and near-IR (YJHKs) light curves of 35 Type Ib/c and Type IIb supernova. This data set is particularly well-suited to explore color relations over a broad wavelength range, and may offer new ways to accurately estimate host galaxy extinction. I will present the photometric sample and results from an initial analysis of the...

  3. 310. Type IIn supernovae: What can we learn from spectra and light curves
    Dr Nikolai Chugai (Institute of astronomy, Russian. Ac. Sci.)

    Type IIn supernovae (SN IIn) is highly diverse and badly understood class with a common feature: they show narrow emission lines indicative of a dense circumstellar matter (CSM). The narrow emission lines could originate either from the undisturbed circumstellar gas excited by X-ray/ultraviolet radiation or from shocked circumstellar clouds. In most SNe IIn the total luminosity is fully...

  4. 387. Dust in Core-Collapse Supernovae
    Dr Ori Fox (NASA/GSFC/ORAU)

    A relatively small number of CCSNe have been observed to exhibit late-time (>100 d) infrared emission from dust over the past 30 years. Since the launch of Spitzer (and now even Herschel), the community has had the capability to probe supernova- associated dust at mid- and far-infrared wavelengths. Combined with ground-based optical and NIR observations, these data have provided...

  5. 365. Theory of dust formation in core-collapse supernovae
    Dr Isabelle Cherchneff (Universitaet Basel)
    11/08/2011, 16:00
    Cosmic dust forms in the circumstellar environments of evolved stars with low and high masses because the synthesis of dust requires high gas densities and temperatures. Supernovae are one of these environments and form dust in their ejecta a few months after their explosion. The harsh physical conditions met in the ejecta and the absence of hydrogen hamper the production of complex...

  6. 374. Light echoes of core collapse supernovae
    Dr Oliver Krause (Max Planck Institute for Astronomy)
    11/08/2011, 16:30
    Young Galactic supernova remnants are unique laboratories for supernova physics. Due to their proximity they provide us with the most detailed view of the outcome of a supernova. However, the exact spectroscopic types of their original explosions have been undetermined so far - hindering to link the wealth of multi-wavelength knowledge about their remnants with the diverse population of...

  7. 369. Spectroscopic Modeling of Core-Collapse Supernovae
    Dr Luc Dessart (Laboratoire d'Astrophysique de Marseille)
    11/08/2011, 17:00
    I will present a new modeling approach that simultaneously computes spectra and light curves and takes into account line blanketing, departures from Local Thermodynamic Equilibrium, time dependent terms in the radiative-transfer, energy, and statistical-equilibrium equations, as well as non-thermal processes associated with radioactive decay. Combined with hydrodynamical inputs of SN...
