The Milky Way and the Local Group (MWLG)
  • Publication
    Three-dimensional decomposition of galaxies with bulge and long bar
    Context. Some observations indicate that the Milky Way has two inner components, a bulge and a long bar, which present a misalignment of Δα ≃ 20° that is...

    Tidally induced velocity gradients in the Milky Way dwarf spheroidal satellites
    We present a kinematic study of six dwarf spheroidal galaxies (dSph) satellites of the Milky Way (MW), namely Carina, Draco, Fornax, Sculptor, Sextans, and Ursa...
  • Publication
    Tidally trapped pulsations in a close binary star system discovered by TESS
    It has long been suspected that tidal forces in close binary stars could modify the orientation of the pulsation axis of the constituent stars. Such stars have...
  • Publication
    Time-domain Study of the Young Massive Cluster Westerlund 2 with the Hubble Space Telescope. I
    Time-domain studies of pre-main-sequence (PMS) stars have long been used to investigate star properties during their early evolutionary phases and to trace the...

    Timing the Evolution of the Galactic Disk with NGC 6791: An Open Cluster with Peculiar High-α Chemistry as Seen by APOGEE
    We utilize elemental-abundance information for Galactic red giant stars in five open clusters (NGC 7789, NGC 6819, M67, NGC 188, and NGC 6791) from the Apache...
  • Publication
    To clump or not to clump. The impact of wind inhomogeneities on the optical and NIR spectroscopic analysis of massive OB stars
    Context. Winds of massive stars have density inhomogeneities (clumping) that may affect the formation of spectral lines in different ways, depending on their...

    TOI-150: A Transiting Hot Jupiter in the TESS Southern CVZ
    We report the detection of a hot Jupiter ({M}p={1.75}-0.17+0.14 {M}{{J}}, R p = 1.38 ± 0.04 R J) orbiting a middle-aged star ({log}g={4.152}-0.043+0.030) in the...

    TOI-519 b: A short-period substellar object around an M dwarf validated using multicolour photometry and phase curve analysis
    Context. We report the discovery of TOI-519 b (TIC 218795833), a transiting substellar object (R = 1.07 R Jup) orbiting a faint M dwarf (V = 17.35) on a 1.26 d...

    Toluene pyrolysis in an electric ARC: Products analysis
    Toluene pyrolysis in a submerged carbon arc produced at least 72 different molecular species as detected by gas-chromatography coupled with mass spectrometry...
