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…
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…
Charged cosmological black holes: a thorough study of a family of solutions
Daniel C. Guariento, Alan Maciel, Marina M. C. Mello +1
We study a class of charged cosmological black holes defined by the Shah-Vaidya solution, which is similar to the McVittie solution but for a central object of nonzero electric cha…
Evolving black holes from conformal transformations of static solutions
Marina M. C. Mello, Alan Maciel, Vilson T. Zanchin
A class of nonstationary spacetimes is obtained by means of a conformal transformation of the Schwarzschild metric, where the conformal factor is an arbitrary function of th…
