Gaia pulsars and where to find them in EDR3
John Antoniadis
The Early Gaia Data Release 3 (EDR3) provides precise astrometry for nearly 1.5 billion sources across the entire sky. A few tens of these are associated with neutron stars in the…
Gaia pulsars and where to find them
John Antoniadis
While the majority of massive stars have a stellar companion, most pulsars appear to be isolated. Taken at face value, this suggests that most massive binaries break apart due to s…
A revisit of PSR J19093744 with 15-year high-precision timing
K. Liu, L. Guillemot, A. G. Istrate +10
We report on a high-precision timing analysis and an astrophysical study of the binary millisecond pulsar, PSR J19093744, motivated by the accumulation of data with well improve…
Measuring Interstellar Delays of PSR J0613-0200 over 7 years, using the Large European Array for Pulsars
R. A. Main, S. A. Sanidas, J. Antoniadis +19
Using data from the Large European Array for Pulsars (LEAP), and the Effelsberg telescope, we study the scintillation parameters of the millisecond pulsar J0613-0200 over a 7 year…
Pre-collapse Properties of Superluminous Supernovae and Long Gamma-Ray Burst Progenitor Models
David R. Aguilera-Dena, Norbert Langer, John Antoniadis +1
We analyze the properties of 42 rapidly rotating, low metallicity, quasi-chemically homogeneously evolving stellar models in the mass range between 4 and 45 at…
Type Ia supernovae from non-accreting progenitors
John Antoniadis, Savvas Chanlaridis, Götz Gräfener +1
Type Ia supernovae (SNe Ia) are manifestations of stars deficient of hydrogen and helium disrupting in a thermonuclear runaway. While explosions of carbon-oxygen white dwarfs are t…
