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 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, 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...
Synchrotron emission from the blazar PG 1553+113. An analysis of its flux and polarization variability
In 2015 July 29-September 1, the satellite XMM-Newton pointed at the BL Lac object PG 1553+133 six times, collecting data for 218 h. During one of these epochs...
Synthesis and FT-IR Spectroscopy of Perdeuterofullerane: C60D36 Evidences of Isotope Effect in the Stability of C60D36
Perdeuterofullerane, C60D36 was synthesized in toluene solution from DCl and Zn. The FT-IR spectrum of C60D36 was compared with that of C60H36, and the C-H...
