Intermediate-resolution (0.5-1 Å) optical spectroscopy of the cataclysmic variable (CV) SY Cnc reveals the spectrum of the donor star. Our data enable us to...
Symbiotic binaries in the Gaia data ─ I. Known symbiotics in DR3 and FPR
Symbiotic stars are long-period interacting binaries composed of an evolved giant and a hot compact companion. Their complex spectra and variability make them...
Symbiotic Stars in the Apache Point Observatory Galactic Evolution Experiment Survey: The Case of LIN 358 and SMC N73 (LIN 445a)
LIN 358 and SMC N73 are two symbiotic binaries in the halo of the Small Magellanic Cloud, each composed of a hot white dwarf accreting from a cool giant...
Symbiotic Stars in the Era of Modern Ground- and Space-Based Surveys
Symbiotic stars, interacting binaries composed of a cool giant and a hot compact companion, exhibit complex variability across the electromagnetic spectrum...
Symbiotic stars, weird novae, and related embarrassing binaries
It has been more than a decade since the last meeting on symbiotic stars and related objects was convened. This year participants gathered in Prague to discuss...
SYMPA, a dedicated instrument for Jovian seismology. I. Principle and performance
Aims:The detection and measurement of acoustic modes on the giant planets of the solar system is of great interest for the study of the internal structure and...
SYMPA, a dedicated instrument for Jovian seismology. II. Real performance and first results
Aims: SYMPA is the first instrument dedicated to the observation of free oscillations of Jupiter. Its principles and theoretical performance have been presented...
Synapses of active galactic nuclei:. Comparing X-ray and optical classifications using artificial neural networks
Context. Many classes of active galactic nuclei (AGN) have been defined entirely through optical wavelengths, while the X-ray spectra have been very useful to...
Synchronous Rotation in the (136199) Eris-Dysnomia System
We combine photometry of Eris from a 6 month campaign on the Palomar 60 inch telescope in 2015, a 1 month Hubble Space Telescope WFC3 campaign in 2018, and Dark...
