| dc.description.abstract | We present an isochrone server for semi-empirical pre-main-sequence model isochrones in the following systems: Johnson-Cousins, Sloan Digital Sky Survey, Two-Micron All-Sky Survey, Isaac Newton Telescope (INT) Wide-Field Camera and INT Photometric Ha Survey (IPHAS)/UV-Excess Survey (UVEX). The server can be accessed via the Cluster Collaboration webpage http://www.astro.ex.ac.uk/people/timn/isochrones/. To achieve this, we have used the observed colours ofmember stars in young clusters with well-established age, distance and reddening to create fiducial loci in the colour-magnitude diagram. These empirical sequences have been used to quantify the discrepancy between the models and data arising from uncertainties in both the interior and atmospheric models, resulting in tables of semi-empirical bolometric corrections (BCs) in the various photometric systems. The model isochrones made available through the server are based on existing stellar interior models coupled with our newly derived semi-empirical BCs. As part of this analysis, we also present new cluster parameters for both the Pleiades and Praesepe, yielding ages of 135+20 -11 and 665+14 -7 Myr as well as distances of 132 ± 2 and 184 ± 2 pc, respectively (statistical uncertainty only). | en_GB |

This research has made use of data obtained at the Isaac Newton
Telescope, which is operated on the island of La Palma by the Isaac
Newton Group (ING) in the Spanish Observatorio del Roque de
los Muchachos of the Institutio de Astrofisica de Canarias. This research
has made use of archival data products from the Two-Micron
All-Sky Survey (2MASS), which is a joint project of the University
of Massachusetts and the Infrared Processing and Analysis Center,
funded by the National Aeronautics and Space Administration
(NASA) and the National Science Foundation.
This research has made use of public data from the SDSS. Funding
for the SDSS was provided by the Alfred P. Sloan Foundation,
the Participating Institutions, the National Science Foundation, the
US Department of Energy, the National Aeronautics and Space Administration,
the Japanese Monbukagakusho, the Max Planck Society
and the Higher Education Funding Council for England. The
SDSS was managed by the Astrophysical Research Consortium for
the Participating Institutions. | en_GB |
