Identification of the Lithium Depletion Boundary and Age of the Southern Open Cluster Blanco 1
Identification the Lithium Depletion Boundary
2011/1/13
We present results from a spectroscopic study of the very low mass members of the Southern open cluster Blanco 1 using the Gemini-N telescope. We obtained intermediate resolution (R~4400) GMOS spectra...
Identification of H$_2$CCC as a diffuse interstellar band carrier

2010/11/9
We present strong evidence that the broad, di use interstellar bands (DIBs) at 4881 and
5450A are caused by the B 1B1 X 1A1 transition of H2CCC (l-C3H2). The large widths of the
bands are due to th...
Identification of strong photometric activity in the components of LHS 1070
Solar and Stellar Astrophysics (astro-ph.SR)

Activity in low-mass stars is an important ingredient in the evolution of such objects. Fundamental physical properties such as age, rotation, magnetic field are correlated with activity.
