A search for top squark pair production in pp collisions at √{s}=13 TeV is performed using events with a single isolated electron or muon, jets, and a large transverse momentum imbalance. The results are based on data collected in 2016 with the CMS detector at the LHC, corresponding to an integrated luminosity of 35.9 fb-1. No significant excess of

Aims: Already from the initial discoveries of extrasolar planets it was apparent that their population and environments are far more diverse than initially postulated. Discovering circumbinary (CB) planets will have many implications, and in this context it will again substantially diversify the environments that produce and sustain planets. We

Aims.This paper is devoted to an interpretation of Quiet-Sun, spatially-resolved spectropolarimetric observations of the Hanle effect in terms of turbulent weak magnetic field determination. Methods: . Observations: the slit was positioned perpendicular to the limb, and the spatial resolution along the slit was 1 arcsec, leading to a depth probing

Satellite accretion events have been invoked for mimicking the internal secular evolutionary processes of bulge growth tep{Kormendy04}. In order to investigate this question, we perform N-body models of the accretion of satellites onto disk galaxies. A scaling between the primary and the satellite based on the Tully-Fisher relation ensures that the

An analysis based on a comparison between observations and stellar models has been carried out to identify radial modes of oscillations in several multi-periodic delta Scuti stars of the Praesepe cluster (BU, BN, BW and BS Cnc). The assumption that all the stars considered have common parameters, such as metallicity, distance or age, is imposed as

We investigate standing kink magnetohydrodynamic (MHD) oscillations in a prominence fine structure modeled as a straight and cylindrical magnetic tube only partially filled with the prominence material and with its ends fixed at two rigid walls representing the solar photosphere. The prominence plasma is partially ionized and a transverse
