On ageing star clusters using red supergiants independent of the fraction of interacting binary stars [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2020 We use the Binary Population and Spectral Synthesis models to test the recent suggestion that red supergiants can provide an accurate age estimate of a coeval stellar population that is unaffected by interacting binary stars.

Detailed models of interacting short-period massive binary stars [PDF]
Astronomy & Astrophysics, 2021 Context. The majority of massive stars are part of binary systems. In about a quarter of these, the companions are so close that mass transfer occurs while they undergo core hydrogen burning, first on the thermal and then on the nuclear timescale.

Effective-one-body multipolar waveform for tidally interacting binary neutron stars up to merger [PDF]
Physical Review D, 2019 Gravitational-wave astronomy with coalescing binary neutron star sources requires the availability of gravitational waveforms with tidal effects accurate up to merger.

Orbital evolution of potentially habitable planets of tidally interacting binary stars [PDF]
Astronomy & Astrophysics, 2020 We simulate the coupled stellar and tidal evolution of short-period binary stars (orbital period Porb ≲ 8 days) to investigate the orbital oscillations, instellation cycles, and orbital stability of circumbinary planets (CBPs).

AGB winds in interacting binary stars [PDF]
, 2020 We perform numerical simulations to investigate the stellar wind from interacting binary stars. Our aim is to find analytical formulae describing the outflow structure. In each binary system the more massive star is in the asymptotic giant branch and its

IMAGES OF GRAVITATIONAL AND MAGNETIC PHENOMENA DERIVED FROM TWO-DIMENSIONAL BACK-PROJECTION DOPPLER TOMOGRAPHY OF INTERACTING BINARY STARS [PDF]
, 2014 We have used two-dimensional back-projection Doppler tomography as a tool to examine the influence of gravitational and magnetic phenomena in interacting binaries that undergo mass transfer from a magnetically active star onto a non-magnetic main ...

Modeling the Dynamics of Tidally Interacting Binary Neutron Stars up to the Merger [PDF]
Physical Review Letters, 2015 The data analysis of the gravitational wave signals emitted by coalescing neutron star binaries requires the availability of an accurate analytical representation of the dynamics and waveforms of these systems. We propose an effective-one-body model that

Mass-transferring binary stars as progenitors of interacting hydrogen-free supernovae [PDF]
Astronomy & AstrophysicsStripped-envelope supernovae (SNe) are hydrogen-poor transients produced at the end of the life of massive stars that have previously lost most or all of their hydrogen-rich envelope.
