Characterizing six seismic solar analogs observed by Kepler, K2, and HERMES
R. A. GarcÃa, S. Mathur, G. T. Hookway +31
Solar analogs, stars that closely match the fundamental properties of the Sun, provide key benchmarks for testing stellar structure and evolution across different ages and activity…
Tales of stellar and binary co-evolution, told by stellar oscillations -- Binary demographics and their impact on stellar mass, orbits, and age estimates in main-sequence and red-giant stars
Paul G. Beck
Red giants are increasingly used as stellar population tracers due to their well-understood evolution and the availability of asteroseismic observables. However, stellar binarity c…
On the contradictory case of the binary system HD 81809 hosting two pulsating solar-like stars observed by TESS
Maria Pia Di Mauro, Camilla Pezzotti, Nuno Moedas +8
We present a new comprehensive study of HD81809, a nearby binary system of two solar-like stars showing high-amplitude X-ray emission and a well-defined 8-year solar-like magnetic…
Blending-induced beating and emission in the symbiotic star Terz V 2513
J. Merc, J. MikoÅajewska, C. GaÅan +4
We present a detailed analysis of Terz V 2513 (=2MASS J17334728-2719266), a poorly studied symbiotic star. Our motivation was a peculiar beating pattern in its light curves from al…
Is the Symbiotic Recurrent Nova T CrB Late? Recent Photometric Evolution and Comparison with Past Pre-Outburst Behaviour
Jaroslav Merc, Åukasz Wyrzykowski, Paul G. Beck +46
T CrB is a symbiotic recurrent nova that last erupted in 1946. Given its recurrence timescale of approximately 80 years, the next outburst is eagerly anticipated by the astronomica…
