A TESS search for donor-star pulsations in High-Mass X-ray Binaries
Gavin Ramsay, Pasi Hakala, Philip A. Charles
Ground-based optical photometry of the counterparts of High-Mass X-ray Binaries (HMXBs) has revealed the presence of periodic modulations on timescales of ~0.3-0.5 d. More recent s…
Monitoring Observations of SMC X-1's Excursions (MOOSE) I: Program Description and Initial High-State Spectral Results
Kristen C. Dage, McKinley Brumback, Joey Neilsen +8
SMC X-1 has exhibited three super-orbital period excursions since the onset of X-ray monitoring beginning with RXTE's launch in 1995. NICER has recently probed a fourth observed ex…
Transient behavior of three SU UMa-type dwarf novae; AR Pic, QW Ser and V521 Peg
Hélène Szegedi, Philip A. Charles, Pieter J. Meintjes +1
Changes in the supercycle lengths of some SU UMa-type dwarf novae have been detected by other studies, and indicate that the mass transfer rates noticeably decrease over time. We i…
A persistent ultraviolet outflow from an accreting neutron star binary transient
N. Castro Segura, C. Knigge, K. S. Long +31
All disc-accreting astrophysical objects produce powerful outflows. In binaries containing neutron stars (NS) or black holes, accretion often takes place during violent outbursts.…
A Decade of Black-Hole X-ray Binary Transients
Philip A Charles, David A H Buckley, Enrico Kotze +7
The last decade has seen a significant gain in both space and ground-based monitoring capabilities, producing vastly better coverage of BH X-ray binaries during their (rare) transi…
Astrometric excess noise in Gaia EDR3 and the search for X-ray binaries
P. Gandhi, D. A. H. Buckley, P. A. Charles +6
Astrometric noise (AEN) in excess of parallax and proper motion is a potential signature of orbital wobble of individual components in binary star systems. The combination of X-ray…
