Ultraviolet extinction correlation with 3D dust maps using white dwarfs
Snehalata Sahu, Pier-Emmanuel Tremblay, Rosine Lallement +2
Accurate astrometric and photometric measurements from Gaia have led to the construction of 3D dust extinction maps which can now be used for estimating the integrated extinctions…
Backscattered solar Lyman-alpha emission as a tool for the heliospheric boundary exploration
I. Baliukin, J. L. Bertaux, M. Bzowski +4
This review summarizes our current understanding of the outer heliosphere and local interstellar medium (LISM) inferred from observations and modeling of interplanetary Lyman- e…
Discovery of a thin lithium plateau among metal-poor red giant branch stars
A. Mucciarelli, L. Monaco, P. Bonifacio +5
The surface lithium abundance A(Li) of warm metal-poor dwarf stars exhibits a narrow plateau down to [Fe/H]~-2.8 dex, while at lower metallicities the average value drops by 0.3 de…
A catalogue of white dwarfs in Gaia EDR3
N. P. Gentile Fusillo, P. -E. Tremblay, E. Cukanovaite +7
We present a catalogue of white dwarf candidates selected from Gaia early data release three (EDR3). We applied several selection criteria in absolute magnitude, colour, and Gaia q…
Empirical photometric calibration of the Gaia Red Clump: colours, effective temperature and absolute magnitude
L. Ruiz-Dern, C. Babusiaux, F. Arenou +2
Gaia Data Release 1 allows to recalibrate standard candles such as the Red Clump stars. To use those, they first need to be accurately characterised. In particular, colours are nee…
Stability of the interstellar hydrogen inflow longitude from 20 years of SOHO/SWAN observations
Dimitra Koutroumpa, Eric Quémerais, Olga Katushkina +3
Aims. A recent debate on the decade-long stability of the interstellar He flow vector, and in particular the flow longitude, has prompted us to check for any variability in the int…
