Investigation in the region of the open cluster Tr 14
CCD UBVRI imaging photometry was carried out in the area of Tr 14. For the first time, we can have an overall view of the lower main sequence of the cluster. It is fully confirmed the anomalous nature of the extinction law. The distance of Tr 14 is stated in d= 3100 pc while its age, derived by the...

| Sumario: | CCD UBVRI imaging photometry was carried out in the area of Tr 14. For the first time, we can have an overall view of the lower main sequence of the cluster. It is fully confirmed the anomalous nature of the extinction law. The distance of Tr 14 is stated in d= 3100 pc while its age, derived by the fitting of isochrones is about 1x10⁶ yrs. The HR diagram of the cluster shows some stars placed in locations where usually are found contracting stars. Our estimation indicates that an on-going star formation process is taken place with an age spread of 5x10⁶ yrs. |
