The Cluster Collaboration's
Isochrone Server (Version 1.1)
Please send comments and suggestions to
This website allows you to compute solar metallicity semi-empirical
pre-main-sequence isochrones in a variety of photometric systems. The
isochrones presented here are based on existing interior models,
however we have computed semi-empirical bolometric corrections and
colour/effective-temperature relations which we use to transform the
models into colour-magnitude diagram space.
Further details can be found in
Bell et al (2014). Further instructions can be found in our
but you also need to heed our
Changes between versions are noted in our change log.
If you have found the semi-empirical model isochrones on this
server useful, we would be grateful if you would state that they are
based on whichever interior model you adopt (e.g. Baraffe et al. 1998
α=1.9) with the Allard et al. (2012) bolometric corrections and
additional empirical corrections as discussed in Bell et al. (2014),
so as to properly apportion credit where it is due.
