White Dwarfs in the Metal-Rich Open Cluster NGC 6253
Elizabeth J. Jeffery, Fabiola Campos, Alejandra Romero +1
We have obtained 53 images with the filter and 19 images with the filter, each with 600-second exposures of the super metal rich open cluster NGC 6253 with the Gemini-South…
An asteroseismic constraint on the mass of the axion from the period drift of the pulsating DA white dwarf star L19-2
Alejandro H. Córsico, Alejandra D. Romero, Leandro G. Althaus +6
We employ an asteroseismic model of L19-2, a relatively massive ($M_{\star} \sim 0.75 M_{\sun}$) and hot ( K) pulsating DA (H-rich atmosphere) white dwarf…
Two new pulsating low-mass pre-white dwarfs or SX Phenix stars?*
M. A. Corti, A. Kanaan, A. H. Córsico +4
Context. The discovery of pulsations in low-mass stars opens an opportunity for probing their interiors and to determine their evolution, by employing the tools of asteroseismology…
