No Pulsar Companion Around the Nearest Low Mass White Dwarf
Tilemachos M. Athanasiadis, Nataliya K. Porayko, John Antoniadis +5
2MASS J050051.85093054.9 is the closest known low-mass helium-core white dwarf in a binary system. We used three high-band international LOFAR stations to perform a targeted sea…
A Search for Pulsar Companions Around Low-Mass White Dwarfs
Tilemachos M. Athanasiadis, Marina Berezina, John Antoniadis +4
We report on a search for pulsars at the positions of eight low-mass white dwarfs and one higher-mass white dwarf with the 100-m Effelsberg Radio Telescope. These systems have orbi…
Observing superluminous supernovae and long gamma ray bursts as potential birthplaces of repeating fast radio bursts
G. H. Hilmarsson, L. G. Spitler, E. F. Keane +12
Superluminous supernovae (SLSNe) and long gamma ray bursts (LGRBs) have been proposed as progenitors of repeating Fast Radio Bursts (FRBs). In this scenario, bursts originate from…
Orbital and epicyclic frequencies around rapidly rotating compact stars in scalar-tensor theories of gravity
Daniela D. Doneva, Stoytcho S. Yazadjiev, Nikolaos Stergioulas +2
We study the orbital and epicyclic frequencies of particles orbiting around rapidly rotating neutron stars and strange stars in a particular scalar-tensor theory of gravity. We fin…
A Comparison of the Red and Green Coronal Line Intensities at the 29 March 2006 and the 1 August 2008 Total Solar Eclipses: Considerations of the Temperature of the Solar Corona
A. Voulgaris, T. Athanasiadis, J. H. Seiradakis +1
During the total solar eclipse at Akademgorodok, Siberia, Russia, in 1 August 2008, we imaged the flash spectrum with a slitless spectrograph. We have spectroscopically determined…
