A shared accretion instability for black holes and neutron stars
F. M. Vincentelli, J. Neilsen, A. J. Tetarenko +20
Accretion disks around compact objects are expected to enter an unstable phase at high luminosity. One instability may occur when the radiation pressure generated by accretion modi…
Multiwavelength observations of MAXI J1820+070 during its outburst decay and subsequent mini-outburst
M. Özbey Arabacı, E. Kalemci, T. Dinçer +3
We present results from quasi-simultaneous multiwavelength observations of the Galactic black hole X-ray transient MAXI J1820070 during the decay of the 2018 outburst and its en…
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.…
Discovery of thermonuclear (Type I) X-ray bursts in the X-ray binary Swift J1858.6-0814 observed with NICER and NuSTAR
D. J. K. Buisson, D. Altamirano, P. Bult +22
Swift J1858.6-0814 is a recently discovered X-ray binary notable for extremely strong variability (by factors in soft X-rays) in its discovery state. We present the detectio…
Soft X-ray emission lines in the X-ray binary Swift J1858.6-0814 observed with XMM-Newton-RGS: disc atmosphere or wind?
D. J. K. Buisson, D. Altamirano, M. Díaz Trigo +11
We find soft X-ray emission lines from the X-ray binary Swift J1858.6-0814 in data from XMM-Newton-RGS: N VII, O VII and O VIII, as well as notable residuals short of a detection a…
The variable radio counterpart of Swift J1858.6-0814
J. van den Eijnden, N. Degenaar, T. D. Russell +18
Swift J1858.6-0814 is a transient neutron star X-ray binary discovered in October 2018. Multi-wavelength follow-up observations across the electromagnetic spectrum revealed many in…
The Changing-look Optical Wind of the Flaring X-ray Transient Swift J1858.6-0814
T. Muñoz-Darias, M. Armas Padilla, F. Jiménez-Ibarra +15
We present the discovery of an optical accretion disk wind in the X-ray transient Swift J1858.6-0814. Our 90-spectrum data set, taken with the 10.4m GTC telescope over 8 different…
The Be/X-ray binary system V 0332+53: A Short Review
M. D. Caballero-Garcia, A. Camero-Arranz, M. Ozbey Arabaci +1
Be/X-ray binary systems provide an excellent opportunity to study the physics around neutron stars through the study of the behaviour of matter around them. Intermediate and low-lu…
Activity from the Be/X-ray binary system V0332+53 during its intermediate-luminosity outburst in 2008
M. D. Caballero-Garcia, A. Camero-Arranz, M. Ozbey Arabaci +7
Aims: We present a study of the Be/X-ray binary system V 0332+53 with the main goal of characterizing its behavior mainly during the intermediate-luminosity X-ray event on 2008. In…
Detection of a large Be circumstellar disk during X-ray quiescence of XTE J1946+274
M. Ozbey Arabaci, A. Camero-Arranz, J. Gutierrez-Soto +6
We present a multiwavelength study of the Be/X-ray binary system XTE J1946+274 with the main goal of better characterizing its behavior during X-ray quiescence. We aim to shed ligh…
Multiwavelength observations of the black hole transient Swift J1745-26 during the outburst decay
Emrah Kalemci, Mehtap Ozbey Arabaci, Tolga Guver +12
We characterized the broad-band X-ray spectra of Swift J1745-26 during the decay of the 2013 outburst using INTEGRAL ISGRI, JEM-X and Swift XRT. The X-ray evolution is compared to…
Recent activity of the Be/X-ray binary system SAX J2103.5+4545
A. Camero, C. Zurita, J. Gutierrez Soto +6
Aims. We present a multiwavelength study of the Be/X-ray binary system SAX J2103.5+4545 with the goal of better characterizing the transient behaviour of this source. Methods. SAX…
