A new method to estimate the ages of globular clusters: the case of NGC 3201
We devised a new method to estimate globular cluster absolute ages by adopting the knee of the bending of the lower main-sequence (MS) in the Near-Infrared (NIR...
A new calibration method, applicable to multidetector telescopes, is presented. This method is based on the comparison between experimental data and the ones...
A New Near-IR C2 Linelist for an Improved Chemical Analysis of Hydrogen-deficient, Carbon-rich Giants
Diatomic carbon (C2) is ubiquitous in astronomical environments, from comets and stars to translucent clouds and the interstellar medium. In particular, the C2...
A new OSIRIS/GTC and IDS/INT spectroscopic survey of young stars in the sigma Orionis cluster
The young σ Orionis cluster in the Ori OB 1b association is one of the most important clusters for understanding the stellar and substellar formation and...
A new perspective on the solar internal rotation from fitting long and very long time-series.
With some 14, 15 and 29 years of HMI, MDI and GONG observations, respectively, we have reached a new milestone in acquiring almost three decades of nearly...
A new perspective on the solar tachocline from long and very long time-series.
With some 15, 15 and 30 years of MDI, HMI and GONG observations, respectively, we have reached a new milestone in acquiring almost three decades of nearly...
