  • Cosmological Signatures in High S/n Spectra
    The authors review briefly the observational status of abundance determinations for those elements produced in the first seconds of a "standard" Big Bang Universe, showing that although [4He] and [D] appear not to be mutually compatible there is still room for reconciliation via astration of D, for values consistent with estimated [7Li]. New limits

  • Coordination of Astronomical Observations at the Canary 1049.01-ISLANDS
    The Instituto de Astrofisica de Canarias has two observatories on the Canary Islands; Roque de los Muchachos Observatory on La Palma and Teide Observatory, on Tenerife. In this contribution the authors explain the guidelines for the allocation of this observing time and mention some of the future plans for remote observing and control of the

  • Comparison of Solar Oscillation Data Obtained from a Study of the NA and K Fraunhoffer Absorption Lines
    Two independent resonant scattering spectrometers, one using a sodium and the other a potassium vapour cell, were operated simultaneously at the same site. Due to the differing abundances of ground state atoms of these two elements different depths of the photosphere are sampled. An inter-comparison of solar p modes obtained with these

  • Bimodality and Lithium Abundance on the Upper Main Sequence of the Open Cluster NGC 752
    Spectra of resolution λ/Δλ ≡ 2×104 and good S:N ratio are presented in the range containing the 7Li doublet at 6707 Å for 9 main sequence or slightly evolved stars in NGC 752 (age ≡2×109years). The authors investigate the suggested main sequence bimodality using the spectroscopic indications of binarity and high rotational velocity, as well as the

  • Announcement of opportunity: GHRIL.
    PATT and CAT will consider applications for the use of the Groundbased High Resolution Imaging Laboratory (GHRIL) from September 1988. The applications deadline is May 1st 1988. Users outside the UK/NL/SP community can get access to the GHRIL via collaborations or by applying for "international time". This note contains the minimum amount of
