  • MASCARA-2 b (HD185603) light curves and spectra

    In this paper we present MASCARA-2 b, a hot Jupiter transiting the m_V_=7.6 A2 star HD 185603. Since early 2015, MASCARA has taken more than 1.6 million flux measurements of the...
  • Kepler-411 mid-transit times

    We present a detailed characterization of the Kepler-411 system (KOI 1781). This system was previously known to host two transiting planets: one with a period of 3 days...
  • Radial velocities of K2-36

    K2-36 is a K dwarf orbited by two small (R_b_=1.43+/-0.08R_{earth} and R_c=3.2+/-0.3R_{earth}, close-in (a_b=0.022AU and a_c_=0.054AU) transiting planets discovered by the...
  • Spectra of Earth-like planets around M-dwarfs

    The characterisation of the atmosphere of exoplanets is one of the main goals of exoplanet science in the coming decades. We investigate the detectability of atmospheric...
  • HAT-P-32b differential photometry time series

    We obtained 11 photometric time series of secondary eclipse events of the hot Jupiter HAT-P-32b in the Sloan z' band. We inferred the eclipse depth and employed this value to...
  • 47 single-line eclipsing binaries BEBOP velocities

    We introduce the BEBOP radial velocity survey for circumbinary planets. We initiated this survey using the CORALIE spectrograph on the Swiss Euler Telescope at La Silla, Chile....
  • WASP-18b HST/WFC3 spectroscopic phase curves

    We present the analysis of a full-orbit, spectroscopic phase curve of the ultra hot Jupiter (UHJ) WASP-18b, obtained with the Wide Field Camera 3 aboard the Hubble Space...
  • Transiting planet WASP-76

    Binarity is a widespread phenomenon around solar-type stars, including the host stars of transiting extrasolar planets. We performed a detailed study of six transiting planetary...
  • Multiplicity study of transiting exoplanet hosts. I.

    Many main-sequence stars are part of multiple systems. The effect of stellar multiplicity on planet formation and migration, however, is poorly understood. We study the...
  • GJ 740 radial velocities

    M-dwarfs have proven to be ideal targets for planetary radial velocity (RV) searches due to their higher planet-star mass contrast, which favors the detection of low-mass...
  • TESS optical phase curve of KELT-1b

    We present the detection and analysis of the phase curve of KELT-1b at optical wavelengths, analyzing data taken by the Transiting Exoplanet Survey Satellite (TESS). The light...
  • Discovery of the directly imaged planet YSES 2b

    To understand the origin and formation pathway of wide-orbit gas giant planets, it is necessary to expand the limited sample of these objects. The mass of exoplanets derived...
  • Ages of the planet host stars

    Revealing the mechanisms shaping the architecture of planetary systems is crucial for our understanding of their formation and evolution. In this context, it has been recently...
  • Exoplanet host stars SPHERE multiplicity survey

    We are studying the influence of stellar multiplicity on exoplanet systems and, in particular, systems that have been detected via radial-velocity searches. We are specifically...
  • Two Saturn-mass planets around M dwarfs

    The CARMENES radial-velocity survey is currently searching for planets in a sample of 387 M dwarfs. Here we report on two Saturn-mass planets orbiting TYC 2187-512-1...
  • Free-floating planet candidates in Upp Sco and Oph

    A rich population of low-mass brown dwarfs and isolated planetary mass objects has been reported in the Upper Scorpius and Ophiuchus star-forming complex. We investigate the...
  • Young sub-Neptunes orbiting TOI-2076 light curves

    TOI-2076 is a transiting three-planet system of sub-Neptunes orbiting a bright (G=8.9mag), young (340+/-80Myr) K-type star. Although a validated planetary system, the orbits of...
  • LC and RV for HAT-P-15, 17, 21, 26 and 29

    The measurement of the spin-orbit alignment of hot Jupiters, with a range of orbital and physical properties, can provide information about the evolution of the orbits of this...
  • TOI-1807 RV and flux curves

    Great strides have been made in recent years in the understanding of the mechanisms involved in the formation and evolution of planetary systems; despite this, many...
  • Spectra of Earth-like exoplanets Ocean signatures

    Numerical simulations of starlight that is reflected by Earth-like exoplanets predict habitability signatures that can be searched for with future telescopes. We explore...
