Asteroseismic mass and radius of the naked-eye red giant HD145250
arXiv:2505.20542 · doi:10.3847/2515-5172/ade1cd
Abstract
We present the first asteroseismic analysis of the bright, nearby red giant star, HD145250. We calculate the global seismic quantities of the star from single-sector, 2-minute TESS photometry, and determine its mass and radius to be ~1.4 M and ~16 R using asteroseismic scaling relations. Our values agree with published non-seismic mass and radius estimates based on comparisons with stellar evolutionary models.
