Evaluating chemically homogeneous evolution in stellar binaries: Electromagnetic implications -- Ionizing photons, SLSN-I, GRB, Ic-BL
Sohan Ghodla, J. J. Eldridge, Elizabeth R. Stanway +1
We investigate the occurrence of rapid-rotation induced chemically homogeneous evolution (CHE) due to strong tides and mass accretion in binaries. To this end, we generalize the re…
VFTS 243 as predicted by the BPASS fiducial models
H. F. Stevance, S. Ghodla, S. Richards +3
The recent discovery of an unambiguous quiescent BH and main sequence O star companion in VFTS 243 opens the door to new constraints on theoretical stellar evolution and population…
What can Gaussian Processes really tell us about supernova lightcurves? Consequences for Type II(b) morphologies and genealogies
H. F. Stevance, A. Lee
Machine learning has become widely used in astronomy. Gaussian Process (GP) regression in particular has been employed a number of times to fit or re-sample supernova (SN) light-cu…
To be or not to be a black hole: detailed binary population models as a sanity check
H. F. Stevance, S. G. Parsons, J. J. Eldridge
We use the self-consistent stellar populations in the Binary Population A Spectral Synthesis (BPASS) models to assess whether NGC1850-BH1 is a black hole. Using search criteria bas…
Binary pathways to SLSNe-I: SN 2017gci
H. F. Stevance, J. J. Eldridge
Some hydrogen poor superluminous supernovae (SLSNe) exhibit bumps in the tails of their light-curves associated with hydrogen features in their late time spectra. Here we use the e…
Photometric and spectroscopic evolution of the interacting transient AT 2016jbu (Gaia16cfr)
S. J. Brennan, M. Fraser, J. Johansson +68
We present the results from a high cadence, multi-wavelength observation campaign of AT 2016jbu (aka Gaia16cfr), an interacting transient. This dataset complements the current lite…
A systematic aging method I: HII regions D118 and D119 in NGC 300
H. F. Stevance, J. J. Eldridge, A. McLeod +2
Accurately determining the age of H\,{ii} regions and the stars they host is as important as it is challenging. Historically the most popular method has been isochrone fitting to H…
The shape of SN 1993J re-analyzed
H. F. Stevance, D. Baade, J. R. Bruten +8
SN 1993J is one of the best studied Type IIb supernovae. Spectropolarimetric data analyses were published over two decades ago at a time when the field of supernova spectropolarime…
Weighing in on black hole binaries with BPASS: LB-1 does not contain a 70M black hole
J. J. Eldridge, E. R. Stanway, K. Breivik +3
The recent identification of a candidate very massive 70 M(Sun) black hole is at odds with our current understanding of stellar winds and pair-instability supernovae. We investigat…
Spectropolarimetry of stripped envelope core collapse supernovae and their progenitors
H. F. Stevance
Over the past 30 years, spectropolarimetry has proven to be a great tool to probe the 3D geometry of core collapse supernovae (CCSNe). The number of high-quality multi-epoch spectr…
The 3D shape of Type IIb SN 2011hs
H. F. Stevance, J. R. Maund, D. Baade +10
We observed seven epochs of spectropolarimetry in optical wavelengths for the Type IIb SN 2011hs, ranging from -3 to +40 days with respect to V -band maximum. A high degree of inte…
Probing the rotational velocity of Galactic WO stars with spectropolarimetry
H. F. Stevance, R. Ignace, P. A. Crowther +3
Oxygen sequence Wolf-Rayet stars (WO) are thought to be the final evolution phase of some high mass stars, as such they may be the progenitors of type Ic SNe as well as potential p…
Late-time Flattening of Type Ia Supernova Light Curves: Constraints From SN 2014J in M82
Yi Yang, Lifan Wang, Dietrich Baade +11
The very nearby Type Ia supernova 2014J in M82 offers a rare opportunity to study the physics of thermonuclear supernovae at extremely late phases (800 days). Using the Hu…
Spectropolarimetry of the Type IIb SN 2008aq
H. F. Stevance, J. R. Maund, D. Baade +8
We present optical spectroscopy and spectropolarimetry of the Type IIb SN 2008aq 16 days and 27 days post-explosion. The spectrum of SN 2008aq remained dominated by Halpha P Cygni…
