A Multiband Catalog of Infrared-Excess Sources in the Vela-Carina Region: VVVX, DECaPS, and GLIMPSE

R. M. Torres, R. K. Saito, V. Fermiano +4

Multiwavelength surveys of the Galactic midplane enable the identification of infrared-excess sources, signatures of circumstellar material, though high extinction and crowding hin…

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…

The young exoplanetary system TOI-4562: Confirming the presence of a third body in the system

V. Fermiano, R. K. Saito, V. D. Ivanov +11

Young planetary systems represent an opportunity to investigate the early stages of (exo)planetary formation because the gravitational interactions have not yet significantly chang…

A treatment procedure for GMOS/IFU data cubes: application to NGC 2835

R. B. Menezes, T. V. Ricci, J. E. Steiner +3

We present a set of treatment techniques for GMOS/IFU data cubes, including: correction of the differential atmospheric refraction; Butterworth spatial filtering, to remove high sp…

SOAR observations of the high-viscosity accretion disc of the dwarf nova V4140 Sagitarii in quiescence and in outburst

Raymundo Baptista, Bernardo W. Borges, Alexandre S. Oliveira

We report the analysis of 22 B-band light curves of the dwarf nova V4140 Sgr obtained with SOI/SOAR during two nights along the decline of a superoutburst in 2006 Sep 12-24 and in…
