Lyngå 1, A Small Open Cluster Containing a Red-Supergiant Member. (2003). Revista Mexicana De Astronomía Y Astrofísica, 39(2), 89-105. https://astronomia.unam.mx/journals/rmxaa/article/view/2003rmxaa..39...89v
Abstract
We present CCD {UBV}RI} (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 E(B-V)= 0.45+/-0.03, the ratio A[V]/E(B-V)= R suggests that the extinction law may be slightly anomalous ( R ≈ 3.5) and that the cluster distance modulus is V0 - M[V] = 11.40+/-0.2. The age of Lyngå 1 is between 100 and 125 Myr according to a fitting of theoretical isochrones, 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.Similar Articles
