Orbital and sub-orbital period determination of the candidate high-mass X-ray binary HD 3191
Josep Martí, Pedro L. Luque-Escamilla, Estrella Sánchez-Ayaso +1
The final aim of this paper is to expand the sparse group of X-ray binaries with gamma-ray counterparts as laboratories to study high-energy processes under physical conditions tha…
A blazar as the likely counterpart to 4FGL J0647.7-4418 instead of a gamma-ray binary
Josep Martí, Estrella Sánchez-Ayaso, Pedro L. Luque-Escamilla +3
The persistent gamma-ray source 4FGL J0647.7-4418 is tentatively associated in the latest Fermi catalogue with the sub-dwarf O-type X-ray binary HD 49798. However, an AGN candidate…
Detection of optical flickering from the symbiotic Mira-type binary star EF Aquilae
V. V. Dimitrov, S. Boeva, J. Martí +8
We performed photometry with a 1 minute time resolution of the symbiotic stars EF Aquilae, AG Pegasi and SU Lyncis in Johnson B and V band. Our observations of the symbiotic Mira-t…
The radio jets of SS 433 at millimetre wavelengths
Josep Martí, Irene Bujalance-Fernández, Pedro L. Luque-Escamilla +3
Context. SS 433 is historically a well-known microquasar in the Galaxy that has been deeply studied during the four decades elapsed since its discovery. However, observations at ve…
Possible Association of Two Stellar Bowshocks with Unidentified Fermi Sources
E. Sánchez-Ayaso, María V. del Valle, J. Martí +2
The bowshocks of runaway stars had been theoretically proposed as gamma-ray sources. However, this hypothesis has not been confirmed by observations up to date. In this paper, we p…
