Description
Since September 2007 we have been monitoring the optical counterpart (V, R and i-bands) of the black hole X-ray binary GX 339-4 with the Faulkes Telescope South situated at Siding Spring in Australia. The source has continued to decline from its 2006-7 outburst (ATel #968) until May 2008, in which a period of strong variability began. At its faintest flux level, on 2008-04-29 (MJD 54585.51) the magnitudes were V = 18.39 +- 0.06; R = 18.10 +- 0.03; i = 17.22 +- 0.03.

    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

    Finding Water Worlds with Transit Timing Variations

    Models predict that planets with water-rich compositions may be common around low-mass stars, but definitive evidence for the existence of water worlds has remained elusive. Precise mass and radius measurements for small planets allow us to identify candidate water worlds that have bulk densities too low to be consistent with a rocky composition

    First light and results for atmospheric characterization with The Near Infra-Red Planet Searcher (NIRPS)

    NIRPS is a new fiber-fed high spectral resolution (~80k) spectrograph assisted by adaptive optics installed on the 3.6m telescope of ESO at LaSilla, Chile. Operated simultaneously with HARPS, NIRPS covers the Y, J, and H bands. The commissioning phase demonstrated high stability for time-series observations along precise radial velocities reaching
