Beyond the Nyquist frequency: Asteroseismic catalog of undersampled Kepler late subgiants and early red giants
B. Liagre, R. A. GarcÃa, S. Mathur +9
Subgiants and early red giants are crucial for studying the first dredge-up, a key evolutionary phase where the convective envelope deepens, mixing previously interior-processed ma…

Singular bifurcations in a modified Leslie-Gower model
Roberto Albarran GarcÃa, Martha Alvarez-RamÃrez, Hildeberto Jardón-Kojakhmetov
We study a predator-prey system with a generalist Leslie-Gower predator, a functional Holling type II response, and a weak Allee effect on the prey. The prey's population often gro…

Kepler meets Gaia DR3: homogeneous extinction-corrected color-magnitude diagram and binary classification
D. Godoy-Rivera, S. Mathur, R. A. GarcÃa +8
The original Kepler mission has delivered unprecedented high-quality photometry. These data have impacted numerous research fields (e.g., asteroseismology and exoplanets), and cont…
