HW Vir systems are rare eclipsing binary systems including a subdwarf B star (sdB) with a faint companion, mostly M-dwarfs. Up to now, 19 HW Vir systems have been published, three of them with substellar companions. We report the spectroscopic as well as photometric observation of the eclipsing sdB binary PTF1 J011339.09+225739.1 (PTF1 J0113) in a

Context. The relative abundance of the dust grain types in the interstellar medium is directly linked to physical quantities that trace the evolution of galaxies. Because of the poor spatial resolution of the infrared and submillimetre data, we are able to study the dependence of the resolved infrared spectral energy distribution (SED) across

The performance of the "weighted Fourier phase slope" centroiding algorithm at the subpupil image of a Shack-Hartmann wavefront sensor for point-like astronomical guiding sources is explored. This algorithm estimates the image's displacement in the Fourier domain by directly computing the phase slope at several spatial frequencies, without the

A search for resonancelike structures in the Bs0π± invariant mass spectrum is performed using proton-proton collision data collected by the CMS experiment at the LHC at √{s }=8 TeV , corresponding to an integrated luminosity of 19.7 fb-1 . The Bs0 mesons are reconstructed in the decay chain Bs0→J /ψ ϕ , with J /ψ →μ+μ- and ϕ →K+K-. The Bs0π±

Results are presented from a search for supersymmetry in events with a single electron or muon and hadronic jets. The data correspond to a sample of proton-proton collisions at √{ s } = 13TeV with an integrated luminosity of 35.9fb-1, recorded in 2016 by the CMS experiment. A number of exclusive search regions are defined according to the number of

A search for new physics using events containing an imbalance in transverse momentum and one or more energetic jets arising from initial-state radiation or the hadronic decay of W or Z bosons is presented. A data sample of proton-proton collisions at √{s }=13 TeV , collected with the CMS detector at the LHC and corresponding to an integrated
