The Exceptionally Luminous Type II-L SN 2008es
A. A. Miller, R. Chornock, D. A. Perley +11
We report on our early photometric and spectroscopic observations of the extremely luminous Type II supernova (SN) 2008es. With an observed peak optical magnitude of m_V = 17.8 and…
The Type IIn Supernova 2010bt: The Explosion of a Star in Outburst
N. Elias-Rosa, S. D. Van Dyk, S. Benetti +12
It is well known that massive stars (M > 8 M_sun) evolve up to the collapse of the stellar core, resulting in most cases as a supernova (SN) explosion. Their heterogeneity is relat…
Circumstellar Medium Constraints on the Environment of Two Nearby Type Ia Supernovae: SN 2017cbv and SN 2020nlb
D. J. Sand, S. K. Sarbadhicary, C. Pellegrino +23
We present deep Chandra X-ray observations of two nearby Type Ia supernovae, SN 2017cbv and SN 2020nlb, which reveal no X-ray emission down to a luminosity 5.3$\time…
Waiting in the Wings: Reflected X-ray Emission from the Homunculus Nebula
M. F. Corcoran, K. Hamaguchi, T. Gull +14
We report the first detection of X-ray emission associated with the Homunculus Nebula which surrounds the supermassive star Eta Carinae. The emission is characterized by a temperat…
A Spectroscopic Study of Mass Outflows in the Interacting Binary RY Scuti
E. D. Grundstrom, D. R. Gies, T. C. Hillwig +5
The massive interacting binary RY Scuti is an important representative of an active mass-transferring system that is changing before our eyes and which may be an example of the for…
Enormous explosion energy of Type IIP SN 2017gmr with bipolar Ni-56 ejecta
V. P. Utrobin, N. N. Chugai, J. E. Andrews +7
The unusual Type IIP SN 2017gmr is revisited in order to pinpoint the origin of its anomalous features, including the peculiar light curve after about 100 days. The hydrodynamic mo…
