PublicationTowards a more complete sample of binary central stars of planetary nebulae with Gaia
Context. Many if not most planetary nebulae (PNe) are now thought to be the outcome of binary evolutionary scenarios. However, only a few percent of the PNe in...

PublicationTowards a new classification of galaxies: principal component analysis of CALIFA circular velocity curves
We present a galaxy classification system for 238 (E1-Sdm) CALIFA (Calar Alto Legacy Integral Field Area) galaxies based on the shapes and amplitudes of their...

GrantTowards the understanding of the late stages of stellar evolution and the formation of complex organic molecules
Most of the stars (M < 8 solar masses, Ms) end their lives with a phase of strong mass loss on the Asymptotic Giant Branch (AGB), just before they form...

PublicationTracing Chemical Evolution over the Extent of the Milky Way's Disk with APOGEE Red Clump Stars
We employ the first two years of data from the near-infrared, high-resolution SDSS-III/APOGEE spectroscopic survey to investigate the distribution of...

PublicationTracing the stellar component of low surface brightness Milky Way dwarf galaxies to their outskirts. I. Sextans
Aims: We present results from deep and very spatially extended CTIO/DECam g and r photometry (reaching out to 2 mag below the oldest main-sequence turn-off and...

PublicationTracking Advanced Planetary Systems (TAPAS) with HARPS-N . I. A multiple planetary system around the red giant star TYC 1422-614-1
Context. Stars that have evolved off the main sequence are crucial for expanding the frontiers of knowledge on exoplanets toward higher stellar masses and for...

PublicationTraMoS project - III. Improved physical parameters, timing analysis and starspot modelling of the WASP-4b exoplanet system from 38 transit observations
We report 12 new transit observations of the exoplanet WASP-4b from the Transit Monitoring in the South (TraMoS) project. These transits are combined with all...

PublicationTransformations between 2MASS, SDSS and BVRI photometric systems: bridging the near-infrared and optical
We present colour transformations for the conversion of the Two Micron All Sky Survey (2MASS) photometric system to the Johnson-Cousins UBVRI system and further...
