The Evolutionary Status of High-lithium, High-activity Cool Dwarfs
نویسنده
چکیده
We have used the newly available Hipparcos parallaxes to study the evolutionary status of a number of high-lithium, high-activity late-type dwarfs found in X-ray based surveys, i.e. the Einstein Extended Medium Sensitivity Survey and the Einstein Slew Survey. The sample stars are placed on evolutionary tracks thus estimating their age.

Keck Observation of Lithium in a Cool Halo Dwarf CommonProper Motion
We exploit the uniform age and initial chemical composition of the halo common proper motion pair, HD 134439 and HD 134440, to eliminate metallicity{ and age{dependent eeects in an investigation of Li processing in cool, metal{poor dwarfs. We have obtained a very high S/N (480) Keck observation of Li in HD 134440, and derive a 3 upper limit on its lithium abundance of A(Li) ?0:59. This contrast...
متن کاملX-ray emission of brown dwarfs: Towards constraining the dependence on age, luminosity, and temperature
We observed brown dwarfs in different evolutionary stages with the Chandra X-ray Observatory with the aim to disentangle the influence of different stellar parameters on the X-ray emission of substellar objects. The ages of our three targets (HR 7329 B, Gl 569 Bab, and HD 130948 BC) are constrained by them being companions to main-sequence stars of known age. With both known age and effective t...
متن کامل2 High resolution spectroscopy of ultracool M dwarfs
We present high-resolution echelle spectroscopy of thirty-nine dwarfs with spectral types between M6.5 and L0.5. With one exception, those dwarfs were selected from the 2MASS database using photometric criteria, (J-KS) ≥ 1.1 and KS ≤ 12.0, and therefore should provide a sample free of the kinematic biases which can affect proper-motion selected samples. Two of the stars, 2MASSI 0253202+271333 a...
متن کاملAn Improved Optical Spectrum and New Model Fits of
Long thought by some researchers to be an oddity, GD 165B has instead proven to be the rst example of a class of very cool objects (the L dwarfs) which, due to dust formation in their photospheres, lack the dominant bands of TiO seen in warmer M dwarfs. Here we present an improved optical (6200{10300 A) spectrum of GD 165B and identify its prominent spectral features. Among these are newly iden...
