    2.2 micron survey of the Galactic bulge and plane

    A near-IR survey is conducted in order to penetrate the dust of the Galactic plane through the K window and study the flux from Rayleigh-Jeans tail emission in...

    A Massive Hot Jupiter Orbiting a Metal-rich Early M Star Discovered in the TESS Full-frame Images

    Observations and statistical studies have shown that giant planets are rare around M dwarfs compared with Sun-like stars. The formation mechanism of these...

  • Publication
    A survey of faint, near-infrared sources towards the centre of the Galaxy

    The authors present the results of a survey made at 1.65 μm (H) and 2.2 μm (K) in 15 small areas on the galactic equator between l = 0° and l = 10°. 775...

    Carbon abundances and isotope ratios in 70 bright M giants

    Approximate carbon abundances and C-12/C-13 isotope ratios are obtained for 70 M giant stars from intermediate-resolution spectrophotometry of the CO bands near...

    Determination of temperatures and angular diameters of 114 F-M stars using the infrared flux method (IRFM)

    Temperatures and angular diameters are derived for 114 F-M stars using the infrared flux (IRFM) method and initially both the Vega flux calibrations of Dreiling...

    Infrared sources in the compact H II region G45.5 plus 0.1

    Infrared photometric observations (1.25-10 microns) of the compact H II region G45.5 plus 0.1 are reported. Three new sources, which appear pointlike in nature...

    On the evolutionary status of two very active visual binaries

    HD 36705 (AB Doradus) and HD 155555 (V824 Ara) are two nearby very active cool stars. Both have strong Li I (lambda)6708 resonance lines, implying high surface...

    Pre-main sequence lithium burning. 2: Pleiades low mass stars

    As part of a continuing study of the lithium abundances in pre-main sequence (PMS) low mass stars, we present Li observations for 13 K-type and 3 M-type stars...

    Should Eddington concentrate on M stars?

    In a recent preprint, Pepper et al. (2002) evaluate the sensitivity of photon-noise limited transit searches for habitable planets. They conclude that these...
