VVVX near-IR photometry for 99 low-mass stars in the Gaia EDR3 Catalog of Nearby Stars
(2022)
Context. Red dwarf stars, which represent 75% of stars in the Milky Way, can be studied in great detail in the solar neighborhood, where the sample is more complete.Aims. We intend to better characterize red-dwarf candidates ...
Detection of star streams and turbulence in nearby galaxies: power spectrum analysis of spitzer images

Chemical similarities between Galactic bulge and local thick disk red giants: O, Na, Mg, Al, Si, Ca, and Ti
(EDP SCIENCES S A, 2010)
Context. The formation and evolution of the Galactic bulge and its relationship with the other Galactic populations is still poorly understood. Aims. To establish the chemical differences and similarities between the bulge ...
Gaia DR2 white dwarfs in the Hercules stream
(EDP Sciences, 2019-08-28)
Aims. We analyzed the velocity space of the thin- and thick-disk Gaia white dwarf population within 100 pc by searching for signatures of the Hercules stellar stream. We aimed to identify objects belonging to the Hercules ...
The Gaia-ESO Survey: Churning through the Milky Way
(EDP Sciences, 2018-01)
Context. There have been conflicting results with respect to the extent that radial migration has played in the evolution of the Galaxy. Additionally, observations of the solar neighborhood have shown evidence of a merger ...
Mass extinctions, galactic orbits in the solar neighborhood and the Sun: a connection?
(Guarujá, 2014-03-14)
The orbits of the stars in the disk of the Galaxy, and their passages through the Galactic spiral arms, are a rarely mentioned factor of biosphere stability which might be important for long-term planetary climate evolution, ...
The Gaia -ESO survey: separating disk chemical substructures with cluster models∗: evidence of a separate evolution in the metal-poor thin disk
(EDP Sciences, 2016-02)
Context. Recent spectroscopic surveys have begun to explore the Galactic disk system on the basis of large data samples, with spatial
distributions sampling regions well outside the solar neighborhood. In this way, they ...
Mass extinctions, galactic orbits in the solar neighborhood and the Sun: a connection?

The orbits of the stars in the disk of the Galaxy,
and their passages through the Galactic spiral arms,
are a rarely mentioned factor of biosphere stability
which might be important for long-term planetary
climate ...
Millimeter dust emission compared with other mass estimates in N11 molecular clouds in the LMC
(EDP Sciences, 2013)
CO and dust emission at millimeter wavelengths are independent tracers of cold interstellar matter, which have seldom been compared
on the scale of giant molecular clouds (GMCs) in other galaxies. In this study, and for ...
