X-ray observations performed by several missions during the last few decades have provided a very large data base on black hole X-ray binaries. Many of these...

CharlaA cross-match of 2MASS and SDSS: Peculiar L dwarfs and unresolved binaries
We present the completion of a program to cross-correlate the SDSS Data Release 1 and 2MASS Point Source Catalog in search for extremely red L and T dwarfs. The...

CharlaA giant planet candidate transiting a white dwarf
The formation and evolution of planets in general is closely linked to the life of their host star. What happens to the planetary systems at the end stages of...

CharlaA new L-dwarf member of the moderately metal poor triple system HD 221356
We report on the discovery of a fourth component in the HD 221356 star system, previously known to be formed by an F8V, slightly metal-poor primary ([Fe/H]= -0...

CharlaA new simple turbulent dynamo for stellar activity cycle
In marked contrast with the role of differential rotation in the magnetic induction, effect of inhomogeneous global flow in turbulence has been disregarded in...

CharlaA tale of globular clusters formation and evolution. The case of the old, metal-poor globular cluster NGC4372
I will talk about our current understanding of globular cluster (GC) formation and what we have yet to learn about them. I will particularly focus on the...

CharlaAGN activity in Local Luminous Infrared Galaxies
Luminous Infrared Galaxies (LIR=10^11-10^12Lsun) have star formation rates in the range of ~20-200Msun/yr. In the local Universe ~50% LIRGs show AGN or AGN/SB...

CharlaAre magnetic fields shaping PNe?
This question is important because a large fraction of planetary nebulae (about 80%) are bipolar or elliptical rather than spherically symmetric. Modern...

CharlaAsteroseismology in the Gaia Era: A New View of the Milky Way
Time-domain space missions have revolutionized our understanding of stellar physics and stellar populations. Virtually all evolved stars can be detected as...
