Photometric segregation of dwarf and giant FGK stars using the SVO Filter Profile Service and photometric tools
Carlos Rodrigo, Patricia Cruz, John F. Aguilar +18
This paper is focused on the segregation of FGK dwarf and giant stars through narrow-band photometric data using the Spanish Virtual Observatory (SVO) Filter Profile Service and as…
JWST/MIRI Study of the Enigmatic Mid-Infrared Rings in the Planetary Nebula NGC 1514
Michael E. Ressler, Alba Aller, David Jones +3
While NGC 1514 is an elliptical, but complex, planetary nebula at optical wavelengths, it was discovered to have a pair of infrared-bright, axisymmetric rings contained within its…
Advanced Classification of Hot Subdwarf Binaries Using Artificial Intelligence Techniques and Gaia DR3 data
C. Viscasillas Vázquez, E. Solano, A. Ulla +11
Hot subdwarfs are compact blue evolved objects, burning helium in their cores surrounded by a tiny hydrogen envelope. Most models agree on a common envelope binary evolution scenar…
Planetary nebulae seen with TESS: New and revisited short-period binary central star candidates from Cycles 1 to 4
Alba Aller, Jorge Lillo-Box, David Jones
High-precision and high-cadence photometric surveys such as Kepler or TESS are making huge progress not only in the detection of new extrasolar planets but also in the study of a g…
