  • Time-series photometry of variables in NGC 6441

    NGC 6441 is a bulge globular cluster with an unusual horizontal branch morphology and a rich population of RR Lyrae (RRL) and Type II Cepheid (T2C) variables that is unexpected...
  • K corrections as a function of stellar param.

    Relativistic corrections are estimated for classical Cepheids and the Tip of the Red Giant Branch (TRGB stars), to enable future unbiased 1% measurements of Hubble's constant,...
  • Faculae-Spot dominance & rotation periods

    Stellar rotation periods can be determined by observing brightness variations caused by active magnetic regions transiting visible stellar disk as the star rotates. The...
  • Rc-band light curves of 6 lensed QSOs

    We present six new time-delay measurements obtained from Rc-band monitoring data acquired at the MPIA 2.2m telescope at La Silla observatory between October 2016 and February...
  • Large scale mechanical heating in NGC4945

    Understanding the dominant heating mechanism in the nuclei of galaxies is crucial to understand star formation in starbursts (SB), active galactic nuclei (AGN) phenomena and the...
  • V830 Tau VI light curves and RV curves

    Detecting and characterising exoworlds around very young stars (age<=10Myr) are key aspects of exoplanet demographic studies, especially for understanding the mechanisms and...
  • CARMENES input catalogue of M dwarfs. V.

    The relevance of M dwarfs in the search for potentially habitable Earth-size planets has grown significantly in the last years. In our on-going effort of comprehensively and...
  • PN G283.7-05.1 BVRI and RV curves

    We present the discovery and characterisation of the post-common-envelope central star system in the planetary nebula PN G283.7-05.1. Deep images taken as part of the POPIPlaN...
  • NGC 4104 g and r CFHT/Megacam images

    Groups are the most common association of galaxies in the Universe and they are found in different configuration states, such as loose, compact, and fossil groups. We studied...
  • Asteroid (31) Euphrosyne R-band images

    Asteroid (31) Euphrosyne is one of the biggest objects in the asteroid main belt and it is also the largest member of its namesake family. The Euphrosyne family occupies a...
  • NGC 2516 membership list

    We wish to measure the cool star rotation period distribution for the Pleiades-age rich open cluster NGC 2516 and use it to determine whether cluster-to-cluster variations exist...
  • OGLE-III parallax events with Gaia DR2

    Context. Gravitational microlensing is sensitive to compact-object lenses in the Milky Way, including white dwarfs, neutron stars, or black holes, and could potentially probe a...
  • KIC 9832227 light curves

    We revisit the issue of period variation of the recently claimed red nova precursor candidate KIC 9832227. By using the data gathered during the main mission of the Kepler...
  • Pismis 18 photometry and radial velocities

    Pismis 18 is a moderately populated, intermediate-age open cluster located within the solar circle at a Galactocentric distance of about seven kpc. Few open clusters have been...
  • Kepler-17 long-term photometry

    The study of young Sun-like stars is of fundamental importance to understand the magnetic activity and rotational evolution of the Sun. Space-borne photometry by the Kepler...
  • Limb-darkening for TESS, Kepler, Corot, MOST

    One of the biggest problems we can encounter while dealing with the limb-darkening coefficients for stellar atmospheric models with spherical symmetry is the difficulty of...
  • Revised Gaia Data Release 2 passbands

    The European Space Agency mission Gaia has published with its second data release (DR2, Cat. I/345) a catalogue of photometric measurements for more than 1.3 billion...
  • Extinction towards Galactic O stars

    O stars are excellent tracers of the intervening ISM because of their high luminosity, blue intrinsic SED, and relatively featureless spectra. We are currently conducting the...
  • Seven sdB eclipsing binaries data

    We review the eclipse time variations exhibited by seven sdB eclipsing binaries to establish if data collected over the last 2 decades can reliably predict the presence of two...
  • Limb-darkening for TESS satellite

    We present new gravity and limb-darkening coefficients for a wide range of effective temperatures, gravities, metallicities, and microturbulent velocities. These coefficients...
