A definitive census of the IMF of a nearby young massive cluster
Over the past years, we have performed one of the most extensive study of the young (lambda)-Orionis star forming region, combining photometric data from the...
In order to improve the understanding of the process of emergence of magnetic flux on the solar surface, we studied the temporal evolution of an ephemeral...
A Detailed Characterization of the Milky Way Bulge with APOGEE
An important part of the history of the Milky Way is encoded in the dynamics and chemistry of the inner Galaxy, which contains about 30% of its mass. It is only...
A detailed look at chemical abundances in the Magellanic Clouds
We determine elemental abundances of He, N, O, Ne, S, and Ar in Magellanic Cloud planetary nebulae (PNe) using direct methods and a large set of observed ions...
A Detailled 2D Spectroscopic Study of the Central Region of NGC 5253
We present Integral Field Spectroscopy observations of NGC 5253, a very nearby (d ˜ 3.8 Mpc) HII galaxy. This type of observations allows the detailed study of...
A Different Approach to Calculate the Far-Side Seismic Migration
Seismic images of magnetic activity on the far surface of the Sun are calculated using the seismic holography technique. The method is based on the comparison...
A Direct Imaging Search for Substellar-Mass Companions around Solar-Type Stars in the Upper-Sco OB Association
We present first results from our search for brown dwarf and giant planet companions around G and K type stars in the Upper Sco OB association. Our survey is...
