Dynamical formation of long-period exoplanets systems in evolving binary stars

Isabel J. Lima, Rafael R. Sousa, Silvia M. Giuliatti Winter +4

The dynamical formation and evolution of long-period giant exoplanets have not been well constrained due to the few observational parameters. In this study, we explore the dynamica…

Scientific Validation of the SPARC4 Pipeline: Multi-band Imaging, Polarimetry, and Photometric Time Series for Improved Characterization of Transiting Exoplanets

Eder Martioli, Claudia V. Rodrigues, Julio C. N. Campagnolo +14

High-cadence multi-band imaging and polarimetry have important scientific applications in astronomy. Observations of transits of exoplanets are a particular application that requir…

The eclipsing novalike cataclysmic variable CRTS SSS100505 J093417-174421

R. Baptista, A. Bruch, R. Lopes de Oliveira +3

Time-resolved optical photometry, complemented by TESS data and long-term survey light curves, reveals that the transient object CRTS SSS100505 J093417-174421 is an eclipsing noval…

Revisiting the extremely long-period cataclysmic variables V479 Andromedae and V1082 Sagitarii

Gagik Tovmassian, Diogo Belloni, Anna F. Pala +56

The overwhelming majority of CVs have orbital periods shorter than 10 hr. However, a few have much longer periods, and their formation and existence pose challenges for the CV evol…

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…

Symbiotic stars in X-rays IV: XMM-Newton, Swift and TESS observations

Isabel J. Lima, G. Juan M. Luna, Koji Mukai +7

White dwarf symbiotic binaries are detected in X-rays with luminosities in the range of 10 to 10 lumcgs. Their X-ray emission arises either from the accretion disk bo…

The contact binary system TYC 7275-1968-1 as seen by optical, UV and X-ray observations

Isabel J. Lima, Ana C. Mattiuci, G. Juan M. Luna +4

We present an analysis of publicly available X-ray and optical observations of TYC 7275-1968-1, a contact binary, red nova progenitor candidate. The long optical time series of ASA…

The 2021 mutual phenomena involving the Galilean satellites of Jupiter and the inner satellite Thebe

L. M. Catani, M. Assafin, B. E. Morgado +7

Astrometric studies and orbital modeling of planetary moons have contributed significantly to advancing our understanding of their orbital dynamics. These studies require precise p…

Breaking the degeneracy in magnetic cataclysmic variable X-ray spectral modeling using X-ray light curves

Diogo Belloni, Claudia V. Rodrigues, Matthias R. Schreiber +12

We present an analysis of mock X-ray spectra and light curves of magnetic cataclysmic variables using an upgraded version of the 3D CYCLOPS code. This 3D representation of the accr…

Search for magnetic accretion in SW Sextantis systems

I. J. Lima, C. V. Rodrigues, C. E. Ferreira Lopes +9

SW Sextantis systems are nova-like cataclysmic variables that have unusual spectroscopic properties, which are thought to be caused by an accretion geometry having part of the mass…
