Recovering Signals in CoRoT Mission (RSCoRoT): I. Short Period Variable Stars
C. E. Ferreira Lopes, A. Papageorgiou, B. L. Canto Martins +8
The CoRoT (Convection, Rotation, and planetary Transits) mission still holds a large trove of high-quality, underused light curves with excellent signal-to-noise and continuous cov…
A portrait of the rotation of Ultra-Cool Dwarfs revealed by TESS
D. O. Fontinele, P. D. S. de Lima, Y. S. Messias +7
This study presents the results of a search for rotation signature in 250 Gaia DR3 Ultra-Cool Dwarfs (UCDs) with TESS light curves. We identified 71 targets with unambiguous period…
Pulsation in TESS Objects of Interest
R. L. Gomes, B. L. Canto Martins, D. O. Fontinele +11
We report the discovery of three Transiting Exoplanet Survey Satellite Objects of Interest (TOI) with signatures of pulsation, observed in more than one sector. Our main goal is to…
On the behaviour of spin-orbit connection of exoplanets
Bruno L. Canto Martins, Yuri S. Messias, Maria I. Arruda Gonçalves +5
Star-planet interactions play, among other things, a crucial role in planetary orbital configurations by circularizing orbits, aligning the star and planet spin and synchronizing s…
A dearth of close-in planets around rapidly rotating stars or a dearth of data?
Y. S. Messias, L. L. A. de Oliveira, R. L. Gomes +4
A dearth of close-in planets orbiting rapid rotators was reported almost a decade ago. According to this view only slowly spinning stars with rotation periods longer than 5-10 days…
Rotation signature of TESS B-type stars. A comprehensive analysis
L. F. Barraza, R. L. Gomes, Y. S. Messias +11
Stellar rotation is a fundamental observable that drives different aspects of stellar and planetary evolution. In this work, we present an unprecedented manifold analysis of 160 B-…
Cosmic Shear in Harmonic Space from the Dark Energy Survey Year 1 Data: Compatibility with Configuration Space Results
H. Camacho, F. Andrade-Oliveira, A. Troja +96
We perform a cosmic shear analysis in harmonic space using the first year of data collected by the Dark Energy Survey (DES-Y1). We measure the cosmic weak lensing shear power spect…
Galaxy Clustering in Harmonic Space from the Dark Energy Survey Year 1 Data: Compatibility with Real-Space Results
F. Andrade-Oliveira, H. Camacho, L. Faga +70
We perform an analysis in harmonic space of the Dark Energy Survey Year 1 Data (DES-Y1) galaxy clustering data using products obtained for the real-space analysis. We test our pipe…
A search for rotation periods in 1000 TESS objects of interest
Bruno L. Canto Martins, Roseane L. Gomes, Yuri S. Messias +8
The high quality light curves from the Transiting Exoplanet Survey Satellite (TESS) represent a unique laboratory for the study of stellar rotation, a fundamental observable drivin…
Dark Energy Survey Year 1 Results: galaxy mock catalogues for BAO
S. Avila, M. Crocce, A. J. Ross +51
Mock catalogues are a crucial tool in the analysis of galaxy surveys data, both for the accurate computation of covariance matrices, and for the optimisation of analysis methodolog…
