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…
A Rapid Instrument Exchange System for Humanoid Robots in Minimally Invasive Surgery
Bingcong Zhang, Yihang Lyv, Lianbo Ma +6
Humanoid robot technologies have demonstrated immense potential for minimally invasive surgery (MIS). Unlike dedicated multi-arm surgical platforms, the inherent dual-arm configura…
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…
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…
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…
