PublicaciónThe rotation-metallicity relation for the Galactic disk as measured in the Gaia DR1 TGAS and APOGEE data
Aims: Previous studies have found that the Galactic rotation velocity-metallicity (V-[Fe/H]) relations for the thin and thick disk populations show negative and...

PublicaciónThe rotational broadening of V395 Carinae. Implications on the compact object's mass
Context: The masses previously obtained for the X-ray binary 2S 0921-630 inferred a compact object that was either a high-mass neutron star or low-mass black...

PublicaciónThe Runaway White Dwarf LP400-22 has a Companion
We report the detection of a radial velocity companion to the extremely low-mass white dwarf (WD) LP400-22. The radial velocity of the WD shows variations with...

PublicaciónThe RW Aur microjet: testing MHD disk wind models
We conduct a detailed comparison between the kinematics, morpology and excitation conditions of the RW Aur microjet on scales < 200 AU with predictions from...

PublicaciónThe S2 stream: the shreds of a primitive dwarf galaxy
The S2 stream is a kinematically cold stream that is plunging downwards through the Galactic disc. It may be part of a hotter and more diffuse structure called...

PublicaciónThe S2N2 metallicity calibrator and the abundance gradient of M33
We introduce the log(Hα/[SII]λλ6717+6731) versus log(Hα/[NII]λ6583) (S2N2) diagnostic diagram as a metallicity and ionization parameter indicator for HII...
