Infrared-excess sources in VVV: candidate debris discs, SED characterization, and variability analysis
P. Esteves, R. K. Saito, C. Chavero +9
Debris disks around main-sequence stars provide important insights into planetary formation and evolution; however, identifying these systems in the Galactic plane, where high inte…
New constraints on the binary system HD 327083 and its gaseous and dusty environments
L. Cidale, P. Marchiano, M. Kraus +11
Binary systems with circumbinary molecular and dust rings are of great interest because they provide insights into the dynamics and evolution of stellar systems and the chemistry o…
Pre-main Sequence B Stars Surrounding the Orion Nebula
P. H. F. B. Braz, A. Roman-Lopes, W. J. B. Corradi +6
Pre-main sequence (PMS) early-type stars are rare due to their rapid evolution. Confirming PMS B stars is accordingly valuable for constraining higher mass star formation scenarios…
PKS 2155-304: Long-Term Optical Photometric Monitoring and Variability Analysis
J. L. Weiss, I. Andruchow, E. J. Marchesini +6
Through the detailed study of the optical flux behaviour in blazars over time, it is possible to infer the conditions responsible for their observed emission. PKS 2155-304, a BL La…
Variables in S-PLUS: I. Multiband period-luminosity relations and reddening maps of the Magellanic Clouds using classical Cepheids
Debasish Hazarika, Carlos E. Ferreira Lopes, Márcio Catelan +12
Aims. Classical Cepheids (CCs) are fundamental standard candles for the extragalactic distance scale through their period-luminosity (P-L) relations. Although well calibrated in br…
Tuning ergodicity breaking: Anomalous diffusion under asymptotic power-law forcing
Raul V. B. Morás, M. Florencia Carusela, Luciano C. Lapas
In non-Markovian systems, distinct dynamical phases arise from the competition between internal memory and external forcing, encompassing thermalization, persistent ergodicity brea…
