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-…
TOI-269 b: An eccentric sub-Neptune transiting a M2 dwarf revisited with ExTrA
M. Cointepas, J. M. Almenara, X. Bonfils +59
We present the confirmation of a new sub-Neptune close to the transition between super-Earths and sub-Neptunes transiting the M2 dwarf TOI- 269 (TIC 220479565, V = 14.4 mag, J = 10…
Measuring and characterizing the line profile of HARPS with a laser frequency comb
Fei Zhao, G. Lo Curto, L. Pasquini +13
Aims. We study the 2D spectral line profile of HARPS (High Accuracy Radial Velocity Planet Searcher), measuring its variation with position across the detector and with changing li…
A crucial test for astronomical spectrograph calibration with frequency combs
Rafael A. Probst, Dinko Milaković, Borja Toledo-Padrón +23
Laser frequency combs (LFCs) are well on their way to becoming the next-generation calibration sources for precision astronomical spectroscopy. This development is considered key i…
Cosmological evolution of quasar radio emission in the view of multifractality
A. Bewketu Belete, Smain Femmam, Merja Tornikosk +5
Variations in scaling behavior in the flux and emissions of distant astronomical sources with respect to their cosmic time are important l phenomena that can provide valuable infor…
