Evolutionary models for metal-poor low-mass stars. Lower main sequence of globular clusters and halo field stars
We have performed evolutionary calculations of very-low-mass stars from 0.08 to 0.8 M for different metallicites from [M/H]= -2.0 to -1.0 and we have tabulated the mechanical, thermal and photometric characteristics of these models. The calculations include themost recent interior physics and improved non-grey atmosphere models. The models reproduce the entire main sequences of the globular clu...
متن کاملMagnetic field observations of low-mass stars
Direct measurements of magnetic fields in low-mass stars of spectral class M have become available during the last years. This contribution summarizes the data available on direct magnetic measurements in M dwarfs from Zeeman analysis in integrated and polarized light. Strong magnetic fields at kilo-Gauss strength are found throughout the whole M spectral range, and so far all field M dwarfs of...
متن کاملEvolutionary models for low-mass stars and brown dwarfs: uncertainties and limits at very young ages
We analyse pre-Main Sequence evolutionary tracks for low mass stars with masses m ≤ 1.4M⊙ based on the Baraffe et al. (1998) input physics. We also extend the recent Chabrier et al. (2000) evolutionary models based on dusty atmosphere to young brown dwarfs down to one mass of Jupiter. We analyse current theoretical uncertainties due to molecular line lists, convection and initial conditions. Si...
متن کاملThe Ages of Stars: The Horizontal Branch
Horizontal branch (HB) stars have long played a central role in the age debate. These low-mass stars, which burn helium in the core and hydrogen in a shell, are the immediate progeny of the luminous, vigorously mass-losing red giant branch (RGB) stars. Most importantly in the present context, their temperatures depend strongly on their total masses. More specifically, the lower the mass of an H...
متن کاملThe Ages of Pre-main-sequence Stars
The position of pre-main-sequence or protostars in the Hertzsprung–Russell diagram is often used to determine their mass and age by comparison with pre-main-sequence evolution tracks. On the assumption that the stellar models are accurate, we demonstrate that, if the metallicity is known, the mass obtained is a good estimate. However, the age determination can be very misleading because it is s...
