- Descripción
- We present CCD UBVRI (Cousins system) photometric observations complemented with spectroscopic and polarimetric observations that were carried out in the open cluster Lyngå 1. Our data indicate that the cluster reddening is EB−V = 0.45 ± 0.03, the ratio AV/EB−V = R suggests that the extinction law may be slightly anomalous (R ≈ 3.5) and that the cluster distance modulus is V0 − MV = 11.40 ± 0.2. The age of Lyngå 1 is bet ween 100 and 125 Myr according to a fitting of theoretical iso chrones, and the slope of its mass spectrum is x ≈ 1.7. The brightest red star in the field is a cluster member of spectral type K2 II–Ib.
Presentamos observaciones fotométricas CCD UBVRI (sistema de Cousins) complementadas con observaciones espectroscópicas y polarimétricas en el cúmulo abierto Lyngå 1. Nuestros datos indican que el enrojecimiento del cúmulo es EB−V = 0.45 ± 0.03, que la razón AV/EB−V = R sugiere que la ley de extinción puede ser ligeramente anómala (R ≈ 3.5) y que su módulo de distancia es V0 − MV = 11.40 ± 0.2. La edad de Lyngå 1 está comprendida entre 100 y 125 millones de años de acuerdo a un ajuste de isocronas teóricas y la pendiente del espectro de masas es x ≈ 1.7. La estrella roja más brillante del campo es un miembro de este cúmulo, cuyo tipo espectral es K2 II–Ib.
