Sentences with word «isochrone»

Examining each Kepler system individually considering multiple avenues (isochrone mapping, contrast curves, probability of being bound), we suggest two cases for which the techniques most likely agree in their companion detections (detect the same companion star).

We compare these values to model stellar isochrones to constrain the stellar mass to be M * = 1.22 + / - 0.17 Msun.

With a metallicity around 1.12 Sol's and higher chromospheric activity than Sol the star appears to be 2.5 + / -1.8 billion years old — probably younger than Sol's 4.6 billion years (press release), and one analysis of isochrones suggests that the star may only be 2.0 billion years old (Crepp et al, 2012); and Guinan et al, 1999).

& Yi, S. K. Y2 isochrones with an improved core overshoot treatment.

Based on isochrone fitting, the star may be older than Sol at around 5.9 billion years of age (Margaret C. Turnbull, 2004; and Ibukiyama and Arimoto, 2002).

We compare these values to model stellar isochrones to obtain a stellar mass of 0.893 + / - 0.024 solar masses.

Moreover, based on one analysis of isochrones, the star may only be 1.7 billion years old (Guinan et al, 1999).

Using this data, the researchers created an isochrone map — a map of lines connecting locations where a given spike arrived at the same time.

For example, there may be a relevant market by the application of the SSNIP test (see the Office of Fair Trading Guidance Note 1280a (adopted by the Competition and Markets Authority (CMA)-RRB- paras 3.4 to 3.16 (the Guidance Note) and the isochrones by which that market could be defined.
