Precursor Activity Preceding Interacting Supernovae I: Bridging the Gap with SN 2022mop
S. J. Brennan, S. Barmentloo, S. Schulze +41
Over the past two decades, an increasing number of transients have shown luminous activity at their explosion sites weeks to years before an interacting supernova (SN) is observed.…
The effect of stellar rotation on black hole mass and spin
Sohan Ghodla, J. J. Eldridge
The gravitational wave signature of a binary black hole (BBH) merger is dependent on its component mass and spin. If such black holes originate from rapidly rotating progenitors, t…
Observational implications of cosmologically coupled black holes
Sohan Ghodla, Richard Easther, M. M. Briel +1
It was recently suggested that "cosmologically coupled" black holes with masses that increase in proportion to the volume of the Universe might constitute the physical basis of dar…
Sustained super-Eddington accretion around neutron stars & black holes
Sohan Ghodla, J. J. Eldridge
Recently, it was shown that the formation of a photon-trapping surface might not be sufficient to ensure unimpeded super-Eddington (SE) accretion. In light of this finding, here we…
Exploring the impact of IMF and binary parameter stochasticity with a binary population synthesis code
E. R. Stanway, J. J. Eldridge
Low mass star formation regions are unlikely to fully populate their initial mass functions, leading to a deficit of massive stars. In binary stellar populations, the full range of…
Searching for ejected supernova companions in the era of precise proper motion and radial velocity measurements
A. A. Chrimes, A. J. Levan, J. J. Eldridge +7
The majority of massive stars are born in binaries, and most unbind upon the first supernova. With precise proper motion surveys such as Gaia, it is possible to trace back the moti…
The IACOB project VIII. Searching for empirical signatures of binarity in fast-rotating O-type stars
N. Britavskiy, S. Simón-Díaz, G. Holgado +6
The empirical distribution of projected rotational velocities (vsini) in massive O-type stars is characterized by a dominant slow velocity component and a tail of fast rotators. Bi…
Gravitational wave spectral synthesis
Wouter G. J. van Zeist, J. J. Eldridge, Petra N. Tang
We study the LISA sources that arise from isolated binary evolution, and how these depend on age and metallicity, using model stellar populations from BPASS. We model these as sing…
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…
New constraints on the Bray conservation-of-momentum natal kick model from multiple distinct observations
S. M. Richards, J. J. Eldridge, M. M. Briel +2
Natal supernova kicks, the linear momentum compact remnants receive during their formation, are an essential part of binary population synthesis (BPS) models. Although these kicks…
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…
Towards an understanding of long gamma-ray burst environments through circumstellar medium population synthesis predictions
A. A. Chrimes, B. P. Gompertz, D. A. Kann +8
The temporal and spectral evolution of gamma-ray burst (GRB) afterglows can be used to infer the density and density profile of the medium through which the shock is propagating. I…
Understanding the high-mass binary black hole population from stable mass transfer and super-Eddington accretion in BPASS
M. M. Briel, H. F. Stevance, J. J. Eldridge
With the remarkable success of the LVK consortium in detecting binary black hole mergers, it has become possible to use the population properties to constrain our understanding of…
WO-Type Wolf-Rayet Stars: the Last Hurrah of Massive Star Evolution
Erin Aadland, Philip Massey, D. John Hillier +3
Are WO-type Wolf Rayet (WR) stars in the final stage of massive star evolution before core-collapse? Although WC- and WO-type WRs have very similar spectra, WOs show a much stronge…
The Dependence of Theoretical Synthetic Spectra on -enhancement in Young, Binary Stellar Populations
C. M. Byrne, E. R. Stanway, J. J. Eldridge +2
The enhancement of elements such as oxygen is an important phase in the chemical evolution of the early Universe, with nebular material becoming enriched in these elements soon…
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…
Estimating Transient Rates from Cosmological Simulations and BPASS
M. M. Briel, J. J. Eldridge, E. R. Stanway +2
The detection rate of electromagnetic (EM) and gravitational wave (GW) transients is growing exponentially. As the accuracy of the transient rates will significantly improve over t…
Numerical experiments to help understand cause and effect in massive star evolution
Eoin Farrell, Jose Groh, Georges Meynet +1
The evolution of massive stars is affected by a variety of physical processes including convection, rotation, mass loss and binary interaction. Because these processes modify the i…
Comparing Compact Object Distributions from Mass- and Presupernova Core Structure-based Prescriptions
Rachel A. Patton, Tuguldur Sukhbold, J. J. Eldridge
Binary population synthesis (BPS) employs prescriptions to predict final fates, explosion or implosion, and remnant masses based on one or two stellar parameters at the evolutionar…
Forward Modelling the O3(a+b) GW transient mass distributions with BPASS by varying compact remnant mass and SNe kick prescriptions
Sohan Ghodla, Wouter G. J. van Zeist, J. J. Eldridge +2
We present forward modeling from the BPASS code suite of the population of observed gravitational wave (GW) transients reported by the LIGO/VIRGO consortium (LVC) during their thir…

S. J. Brennan, M. Fraser, J. Johansson +67
We present the bolometric lightcurve, identification and analysis of the progenitor candidate, and preliminary modelling of AT2016jbu (Gaia16cfr). We find a progenitor consistent w…

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…
The Uncertain Masses of Progenitors of Core Collapse Supernovae and Direct Collapse Black Holes
Eoin Farrell, Jose Groh, Georges Meynet +1

Impact of binary interaction on the evolution of blue supergiants
Eoin Farrell, Jose Groh, Georges Meynet +5
A large fraction of massive stars evolve in interacting binary systems, which dramatically modifies the outcome of stellar evolution. We investigated the properties of blue supergi…
