A new deepening of mass-radius empirical relation for main sequence stars
In the following paper I have compared some typical mass-radius relations for main sequence stars by studying their level of agreement with DEBCat (J. Southworth, ASP Conf. Ser. 496 (2015), https://doi.org/10.48550/arXiv.1411.1219, https://www.astro.keele.ac.uk/jkt/debcat/debs.dat), which is a recen...

| description | In the following paper I have compared some typical mass-radius relations for main sequence stars by studying their level of agreement with DEBCat (J. Southworth, ASP Conf. Ser. 496 (2015), https://doi.org/10.48550/arXiv.1411.1219, https://www.astro.keele.ac.uk/jkt/debcat/debs.dat), which is a recent catalog by J. Southworth. Models chosen for testing were originally developed using older, smaller datasets than DEBCat. Each model follows a two-piece function structure, where each branch is a monomial power-law. This approach is motivated by theoretical considerations suggesting that low-mass and high-mass main sequence stars exhibit distinct behaviors in energy production and transport. Best level of agreement with DEBCat is found for Zamorano’s model (J. Zamorano, A. Gimenez, A strophys. Space Sci. 114 (1985), https://doi.org/10.1007/bf00653969). Also a new empirical relation is proposed by fitting a two-piece monomial power-law to DEBCat main sequence stars. |
