Spectral morphology in the open clusters Tr 14 and Tr 15
We have observed 21 stars in the field of Trumpler 15 and 14 stars in the field of Trumpler 14 in order to provide spectral types derived through the MK process. We have also obtained the spectroscopic parallaxes for those groups finding that Tr 15 is almost at the same distance from the Sun than Tr...

| Sumario: | We have observed 21 stars in the field of Trumpler 15 and 14 stars in the field of Trumpler 14 in order to provide spectral types derived through the MK process. We have also obtained the spectroscopic parallaxes for those groups finding that Tr 15 is almost at the same distance from the Sun than Tr 16 but the distance modulus for Tr 14 is larger. Trumpler 14, due to its high concentration of O-type stars, is also the youngest of both groups studied in this work and, perhaps, as young as Trumpler 16. |
