Fig. 4


Position of HD 284149 (black squares) on the H-R diagram for the temperatures corresponding to F8 and G1 spectral classification (see Bonavita et al. 2014), for V and Ks band magnitudes (left and right panels, respectively). Over plotted are the 5, 12, 20, 30, and 70 Myr isochrones of solar metallicity from Bressan et al. (2012) and the members of the β Pic moving group (red circles) and Tuc-Hor association (blue circles) with available trigonometric parallax from the list of Pecaut & Mamajek (2013).
