(EDP Sciences, 2022)
      Context. Virtually all known exoplanets reside around stars with M < 2:3 M either due to the rapid evaporation of the protostellar disks or to selection effects impeding detections around more massive stellar hosts. Aims. ...

      Grandjean, A.; Lagrange, A.M.; Meunier, N.; Rubini, P.; Desidera, S.; Galland, F.; Borgnie, S.; Zicher, N.; Messina, S.; Chauvin, Gael; Sterzik, M.; Pantoja, B. (EDP Sciences, 2021)
      Context. The search of close (a less than or similar to 5 au) giant planet (GP) companions with radial velocity (RV) around young stars and the estimate of their occurrence rates is important to constrain the migration ...

P.; Sollerman, J.; Spyromilio, J.; Taubenberger, S.; Valentini, G.; Vennes, S.; Yoshii, Y. (Royal Astronomical Society, 2014-04-11)
      We present new data for five underluminous Type II-plateau supernovae (SNe IIP), namely SN 1999gn, SN 2002gd, SN 2003Z, SN 2004eg and SN 2006ov. This new sample of low-luminosity SNe IIP (LL SNe IIP) is analysed together ...
