... An artist's concept of a terrestrial planet orbiting the star Alpha Centauri B. Image courtesy of Mark Fisher . Does Alpha Centauri Have Planets? ... UCSC graduate student Javiera Guedes used computer simulations of planet formation to show that terrestrial planets are likely to have formed around the star Alpha Centauri B and to be orbiting in the ?habitable zone? where liquid water can exist on the planet?s surface. The researchers then showed that such planets could be observed. ...

... Aims: Today, large ground-based instruments, like VISIR on the VLT, providing diffraction-limited (about 0.3 arcsec) images in the mid-infrared where strong PAH features appear enable us to see the flaring structure of the disks around Herbig Ae stars. Although great progress has been made in modelling the disk with radiative transfer models able to reproduce the spectral energy distribution (SED) of Herbig Ae stars, the constraints brought by images have not been yet fully exploited. ...
