dc.description.abstract |
The putative association between the 10.<sup>d</sup> 8 classical Cepheid TW Nor and the open cluster Lyngå 6 has generated considerable debate in the literature. New JHK<sub>s</sub> photometry in tandem with existing radial velocities for Lyngå 6 stars implies cluster membership for TW Nor and establishes the variable as a high-weight calibrator for classical Cepheid relations. Fundamental mean parameters determined for Lyngå 6 are: d = 1.91 ± 0.10 kpc, E(J−H) = 0.38 ± 0.02, and log τ = 7.9 ± 0.1. The Benedict et al./Turner Galactic VI<sub>c</sub> Wesenheit function was revised using TW Nor's new parameters: W<sub>V I,0</sub> = (−3.37 ± 0.08) log P<sub>0</sub>−2.48 ± 0.08. TW Nor/Lyngå 6 lie beyond the Sagittarius–Carina spiral arm and occupy the Centaurus arm, along with innumerable young Cepheids and clusters (e.g., VW Cen and VVV CL070). |
