Second-order moment equivalence of twisted Gaussian Schell model beams and orbital angular momentum eigenmodes
T. Ferreira, G. Santos, S. Ayala +5
We show that the covariance matrix of any cylindrically symmetric coherent orbital angular momentum (OAM) eigenmode with quantum number takes a universal form depending only…
General diffraction properties of aperiodic slit arrays
Thiago de Souza Ferreira, Daniel Jonathan, Antonio Z. Khoury +1
Fraunhofer diffraction plays a vital role in experimental physics not only because it accurately describes the behaviour of light in the usual propagation limit, but also because i…
A Jupiter analogue and a cold Super-Neptune orbiting the solar-twin star HIP 104045
Thiago Ferreira, Jorge Meléndez, Diego Lorenzo-Oliveira +3
We present the discovery of two planets around the solar twin HIP 104045 via radial velocity data obtained with the ESO/HARPS spectrograph as part of the Solar Twin Planet Search o…
Unveiling short period binaries in the inner VVV bulge
E. Botan, R. K. Saito, D. Minniti +5
Most of our knowledge about the structure of the Milky Way has come from the study of variable stars. Among the variables, mimicking the periodic variation of pulsating stars, are…
VVV survey near-infrared colour catalogue of known variable stars
Fábio R. Herpich, Carlos E. Ferreira Lopes, Roberto K. Saito +4
Context. The Vista Variables in the Via Lactea (VVV) near-infrared variability survey explores some of the most complex regions of the Milky Way bulge and disk in terms of high ext…
The asymptotic evolution of the stellar merger V1309 Sco: a Blue Straggler in the making?
Thiago Ferreira, Roberto K. Saito, Dante Minniti +4
Stellar mergers are estimated to be common events in the Galaxy. The best studied stellar merger case to date is V1309 Sco (= Nova Scorpii 2008) which was originally misclassified…
