The solar, exoplanet and cosmological lithium problems
J. Melendez, I. Ramirez, L. Casagrande +6
We review three Li problems. First, the Li problem in the Sun, for which some previous studies have argued that it may be Li-poor compared to other Suns. Second, we discuss the Li…
Lithium and magnetic fields in giants. HD 232862 : a magnetic and lithium-rich giant star
A. Lèbre, A. Palacios, J. D. do Nascimento +5
We report the detection of an unusually high lithium content in HD 232862, a field giant classified as a G8II star, and hosting a magnetic field. With the spectropolarimeters ESPaD…
Non-gaussian statistics and stellar rotational velocities of main sequence field stars
J. C. Carvalho, J. D. Jr. do Nascimento, R. Silva +1
In this letter we study the observed distributions of rotational velocity in a sample of more than 16,000 nearby F and G dwarf stars, magnitude complete and presenting high precisi…
