VLTI observations of the radii of four small stars The radii and
masses of the four very-low-mass stars now observed with the
VLTI, GJ 205, GJ 887, GJ 191 (also known as "Kapteyn''s star")
and Proxima Centauri (red filled circles; with error bars). For
comparison, planet Jupiter's mass and radius are also plotted
(blue triangle). The two curves represent theoretical models for
stars of two different ages (400 million years - red dashed
curve; 5 billion years - black fully drawn curve; models by
Gilles Charier and collaborators at the Ecole Normale Supérieur
de Lyon, France). As can be seen, theory and observations fit
very well. About the Image |Release date:||29 November 2002|
