Description
We report on the first asteroseismic analysis of solar-type stars observed by Kepler. Observations of three G-type stars, made at one-minute cadence during the first 33.5 days of science operations, reveal high signal-to-noise solar-like oscillation spectra in all three stars: About 20 modes of oscillation can clearly be distinguished in each star. We discuss the appearance of the oscillation spectra, including the presence of a possible signature of faculae, and the presence of mixed modes in one of the three stars.

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

    Kaon physics is at a turning point - while the rare-kaon experiments NA62 and KOTO are in full swing, the end of their lifetime is approaching and the future experimental landscape needs to be defined. With HIKE, KOTO-II and LHCb-Phase-II on the table and under scrutiny, it is a very good moment in time to take stock and contemplate about the

    Nodal Precession of a Hot Jupiter Transiting the Edge of a Late A-Type Star TOI-1518

    TOI-1518b, a hot Jupiter around a late A-type star, is one of the few planetary systems that transit the edge of the stellar surface (the impact parameter b~0.9) among hot Jupiters around hot stars (Cabot et al. 2021). The host star's high rotation speed (Vsini s~85 km s -1) and the planet's nearly polar orbit (λ~120 deg) may cause a nodal

    Observational evidence of different formation mechanisms of Solar System-type architectures across spectral types

    Despite being the most abundant classes of known exoplanets, super-Earths and mini-Neptunes are absent in our Solar System, and the exact reason for this is still unknown. Some models suggest that cold-Jupiters play a major role in the formation of inner low-mass planets. This could explain the current architecture of our Solar System, and the
