Hard-state accretion disk winds from black holes: the revealing case of MAXI J1820+070
T. Muñoz-Darias, F. Jiménez-Ibarra, G. Panizo-Espinar +16
We report on a detailed optical spectroscopic follow-up of the black hole transient MAXI J1820+070 (ASASSN-18ey). The observations cover the main part of the X-ray binary outburst,…
X-ray dips and a complex UV/X-ray cross-correlation function in the black hole candidate MAXI J1820+070
J. J. E. Kajava, S. E. Motta, A. Sanna +3
MAXI J1820+070, a black hole candidate first detected in early March 2018, was observed by XMM-Newton during the outburst rise. In this letter we report on the spectral and timing…
Variable polarisation and Doppler tomography of PSR J1023+0038 - Evidence for the magnetic propeller during flaring?
Pasi Hakala, Jari J. E. Kajava
Transitional millisecond pulsars are systems that alternate between an accreting low-mass X-ray binary (LMXB) state, and a non-accreting radio pulsar state. When at the LMXB state,…
Neutron star mass and radius measurements from atmospheric model fits to X-ray burst cooling tail spectra
J. Nättilä, M. C. Miller, A. W. Steiner +3
Observations of thermonuclear X-ray bursts from accreting neutron stars (NSs) in low-mass X-ray binary systems can be used to constrain NS masses and radii. Most previous work of t…
Long-term optical and X-ray variability of the Be/X-ray binary H 1145-619: discovery of an on-going retrograde density wave
J. Alfonso-Garzón, J. Fabregat, P. Reig +7
Multiwavelength monitoring of Be/X-ray binaries is crucial to understand the mechanisms producing their outbursts. H 1145-619 is one of these systems, which has recently displayed…
Basic parameters of the helium accreting X-ray bursting neutron star in 4U 1820-30
Valery F. Suleimanov, Jari J. E. Kajava, Sergey V. Molkov +4
The ultracompact low-mass X-ray binary 4U 1820-30 situated in the globular cluster NGC 6624 has an orbital period of only 11.4 min which likely implies a white dwarf compa…
