Description
We report a new observation of Nova Vul 2007 (S. Nakano, IAUC 8861) obtained by the Swift X-ray Telescope (XRT) on 2008 June 18. The nova was detected at count rate of 0.023 count/s, representing a decline by a factor of 3 compared with Swift XRT observations obtained during 2007 November- December, and by about 50% compared with the previous observation obtained on 2007 December 27. The XRT spectrum is significantly softer than during the earlier epoch, with a ratio of X-ray counts in the 1-10 keV band to those in the 0.3-1 keV band having declined from about 1.0 to 0.4.

    Workshop summary: Kaons@CERN 2023

    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
