Description
Aims: SYMPA is the first instrument dedicated to the observation of free oscillations of Jupiter. Its principles and theoretical performance have been presented in Paper I. This second paper describes the data processing method, the real instrumental performance and presents the first results of a Jovian observation run, lead in 2005 at Teide Observatory. Methods: SYMPA is a Fourier transform spectrometer which works at a fixed optical path difference. It produces Doppler shift maps of the observed object. The velocity amplitude of Jupiter's oscillations is expected to be below 60 cm s-1. Results: Despite light technical defects, the instrument was demonstrated to work correctly, being limited only by photon noise. A noise level of about 12 cm s-1 was reached on a 10-night observation run, with 21% duty cycle, which is 5 time better than similar previous observations. However, no signal from Jupiter is clearly highlighted.

The principal objectives of this project are: 1) to study the structure and dynamics of the solar interior, 2) to extend this study to other stars, 3) to search for extrasolar planets using photometric methods (primarily by transits of their host stars) and their characterization (using radial velocity information) and 4) the study of the planetary

    NGTS-28Ab: a short period transiting brown dwarf

    We report the discovery of a brown dwarf orbiting a M1 host star. We first identified the brown dwarf within the Next Generation Transit Survey data, with supporting observations found in TESS sectors 11 and 38. We confirmed the discovery with follow-up photometry from the South African Astronomical Observatory, SPECULOOS-S, and TRAPPIST-S, and

    First characterization of the emission behavior of Mrk 421 from radio to very high-energy gamma rays with simultaneous X-ray polarization measurements

    Aims: We have performed the first broadband study of Mrk 421 from radio to TeV gamma rays with simultaneous measurements of the X-ray polarization from IXPE. Methods: The data were collected as part of an extensive multiwavelength campaign carried out between May and June 2022 using MAGIC, Fermi-LAT, NuSTAR, XMM-Newton, Swift, and several optical
