A micronova burst in the intermediate polar IGR J17014-4306
Alexandre S. Oliveira, D. C. Souza, G. J. M. Luna +1
We report the detection of a short optical burst in TESS data of IGR J17014-4306, the eclipsing intermediate polar with the longest known orbital period. The burst lasts 1.56 d and…
The accretion-driven eruption of the recurrent nova T Corona Borealis
Raymundo Baptista, Wagner Schlindwein, Gerardo J. M. Luna
T Corona Borealis (T CrB) is a symbiotic recurrent nova with an yr recurrence interval, the eruptions of which occur on top of a yr long high-brightness sta…
A search for new symbiotic stars in the Milky Way: Using machine learning techniques applied to photometric databases
V. Contreras Rojas, M. Jaque Arancibia, C. E. Ferreira Lopes +8
Symbiotic stars (SySts) are interacting binaries composed of a red giant transferring material to a hot compact star, typically a white dwarf. Although only about 300 systems are c…
No evidence of intrinsic linear polarization in Nova Vel 2025 (V572 Vel)
Isabel J. Lima, Marina M. C. Mello, Claudia V. Rodrigues +3
We report on polarimetric observations of V572 Vel (Nova Vel 2025) conducted on June 26th and July 21st, 2025, shortly after its nova eruption was discovered. Our measurements in t…
Broad Observational Perspectives Achieved by the Accreting White Dwarf Sciences in the XMM-Newton and Chandra Eras
Solen Balman, Marina Orio, Gerardo J. M. Luna
Accreting white dwarf binaries (AWDs) comprise cataclysmic variables (CVs), symbiotics, AM CVns, and other related systems that host a primary white dwarf (WD) accreting from a mai…
Detection of the white-dwarf spin of V1082 Sgr
I. J. Lima, G. Tovmassian, C. V. Rodrigues +9
We report on the discovery of circular polarization modulated with a period of 1.943 +- 0.002 h in the cataclysmic variable V1082 Sgr. These findings unambiguously reveal the rotat…
The EXO-UV program: lastest advances of experimental studies to investigate the biological impact of UV radiation on exoplanets
Ximena C. Abrevaya, Petra Odert, Oscar J. Oppezzo +4
The EXO-UV program is an international, interdisciplinary collaboration between astrophysicists and biologists aimed at expanding the characterization of ultraviolet radiation (UVR…
A new way to find symbiotic stars: accretion disc detection with continuum survey photometry
A. B. Lucy, J. L. Sokoloski, G. J. M. Luna +10
Symbiotic stars are binaries in which a cool and evolved star of luminosity class I-III accretes onto a smaller companion. However, direct accretion signatures like disc flickering…
V407 Lup, an intermediate polar nova
M. Orio, M. Melicherčík, S. Ciroi +6
We present X-ray and optical observations of nova V407 Lup (Nova Lup 2016), previously well monitored in outburst, as it returned to quiescent accretion. The X-ray light curve in 2…
Chandra High Energy Transmission Gratings Spectra of V3890 Sgr
Marina Orio, Jeremy J. Drake, Jan-Uwe Ness +13
The recurrent nova (RN) V3890 Sgr was observed during the 7th day after the onset of its most recent outburst, with the Chandra ACIS-S camera and High Energy Transmission Gratings…
