  • XO-6b: A transiting hot Jupiter around a fast rotating star

    Orbital properties of hot Jupiters depend on the temperature and rotation rate of their host stars. These observed correlations provide some of the very few constraints on their dynamical evolution. However, almost all the objects available to such studies orbit around relatively slow rotators, with stellar rotation periods usually several times

  • XTE J1855-026 is a supergiant X-ray binary

    The eclipsing X-ray pulsar XTE J1855-026 (Corbet & Mukai 2002, ApJ 577, 923) has been unambiguously identified by a recent Swift observation (Romano et al., ATel #1875) with the reddened early-type star proposed as candidate counterpart by Verrecchia et al. (ATel #102). High-quality spectra of the counterpart taken in August 2003 with the 4.2-m WHT

  • Young and very young stars in NGC 3372, the Carina Nebula

    Results are presented of a large-scale imaging photometric study of the stellar population in the northern part of NGC 3372 with a wavelength coverage from 0.33 to 2.5 μ m. All observations were made at Las Campanas Observatory. The sizes of the three stellar clusters, Tr 14, Tr 15 and Tr 16, were determined by means of star counts. Two-colour and

  • Young and very young stars in NGC 3372, the Carina Nebula

    The advantages of using a telescope of large aperture, like the GTC, for mid-infrared imaging are demonstrated. Examples are given to compare the characteristics of the images in the 8 to 13 μ m regime recently taken with the 2.1 m telescope at San Pedro Mártir with those obtained with a 10 meter class telescope. Finally, 10μ m images of the BN/KL

  • Young T-dwarf candidates in IC 348

    Context: The determination of the lower-end of the initial mass function (IMF) provides strong constraints on star formation theories. Aims: We report here on a search for isolated planetary-mass objects in the 3 Myr-old star-forming region IC 348. Methods: Deep, narrowband CH4off and CH4on images were obtained with CFHT/WIRCam over 0.11 sq. deg
