  • Neutron stars in NGC 5139

    The Chandra/ACIS-I detectors observed NGC 5139 in imaging mode for two continuous periods (2000 January 24 02:15-09:46 and January 25 04:33-17:24 TT) for a total exposure of...
  • Circumstellar disks in the Upper Sco association

    We have performed a survey for new members of the Upper Sco association that have circumstellar disks using mid-infrared photometry from the Wide-field Infrared Survey Explorer...
  • K2 Campaign 2: young disk-bearing stars in Sco & Oph

    The K2 Mission has photometrically monitored thousands of stars at high precision and cadence in a series of ~80-day campaigns focused on sections of the ecliptic plane. During...
  • Properties for exoplanets with Spitzer light curves

    We present a uniform assessment of existing near-infrared Spitzer Space Telescope observations of planet-bearing stars. Using a simple four-parameter blackbody thermal model, we...
  • Modeling Faraday structures. I. 1100-1400 MHz

    Faraday rotation measures (RMs) and more general Faraday structures are key parameters for studying cosmic magnetism and are also sensitive probes of faint ionized thermal gas....
  • OGLE-II DIA microlensing events

    We present a sample of microlensing events discovered in the Difference Image Analysis (DIA) of the OGLE-II images collected during three observing seasons, 1997-1999. 4424...
  • OGLE-II DIA BUL_SC1 field

    We present an implementation of the difference image photometry based on the Alard and Lupton optimal PSF matching algorithm. The most important feature distinguishing this...
  • OGLE microlensing events in Galactic Bulge

    We present the Catalog of microlensing events detected toward the Galactic bulge in three observing seasons, 1997-1999, during the OGLE-II microlensing survey. The search for...
  • Faraday tomography of LoTSS-DR2 - outer Galaxy

    We conducted a follow-up study on the analysis of the LOw Frequency ARray (LOFAR) Two-metre Sky Survey (LoTSS) mosaic in the high-latitude outer Galaxy presented in the first...
  • Dormant 33 solar-masses black hole

    We announce the serendipitous discovery of a nearby (590pc) binary system composed of an old very metal-poor giant star orbiting a black hole with an estimated mass of...
  • Magnetic moments of rocky planets

    For a planet to be considered habitable on its surface, it is an important advantage for it to have a magnetic field that protects its atmosphere from stellar winds as well as...
  • Detection and characterization of TOI-1759 b

    We report the detection and characterization of the transiting sub-Neptune TOI-1759 b, using photometric time-series from TESS and near infrared spectropolarimetric data from...
  • Long-period Ap stars discovered with TESS data

    The rotation periods of the magnetic Ap stars span five to six orders of magnitude. While it is well established that period differentiation must have taken place at the...
  • ZDI maps of five young solar-type stars

    The magnetic activity of the Sun changes with the solar cycle. Similar cycles are found in other stars as well, but their details are not known to a similar degree....
  • Spectra of IRAS 17449+2320

    We report the first detection of the magnetic field in a star of FS CMa type, a subgroup of objects characterized by the B[e] phenomenon. The split of magnetically sensitive...
  • NGC 4666 polarization maps

    The observation of total and linearly polarized synchrotron radiation of spiral galaxies in the radio continuum reveals the distribution and structure of their magnetic fields....
  • Radial Velocity and BIS measurements of Polaris

    We investigate temporally changing variability amplitudes and the multi- periodicity of the type-I Cepheid Polaris using 162 high-precision radial velocity (RV) and bisector...
  • 6.7GHz methanol maser polarization in MSFRs IV

    Magnetohydrodynamical simulations show that the magnetic field can drive molecular outflows during the formation of massive protostars. The best probe to observationally measure...
  • Starspot rotation rates vs. activity cycle phase

    During the solar magnetic activity cycle the emergence latitudes of sunspots change, leading to the well-known butterfly diagram. This phenomenon is poorly understood for other...
  • Intermediate-mass T Tau stars spectra

    The origin of the fossil magnetic fields detected in 5 to 10% of intermediate-mass main sequence stars is still highly debated. We want to bring observational constraints to a...
