Published 1994Staff ViewISSN: 1572-946XSource: Springer Online Journal Archives 1860-2000Topics: PhysicsNotes: Abstract The displacement of a radio-emitting star around the barycenter of a possible planetary system can be measured by astrometric very long baseline interferometry (VLBI) observations. We have observed the radio-emitting starσ 2 CrB at 8 epochs over 5 years by VLBI and fitted its 5 astrometric parameters to the observed coordinates. The post-fit coordinate residuals have an rms scatter of 0.22 milliarcseconds and show no systematic behavior. We use this result to set a limit on the presence of planets aroundσ 2 CrB and conclude that our present VLBI astrometric precision corresponds to the threshold to detect a Jupiter-like planet around this star. We also discuss the astrometric monitoring program of 11 radio-emitting stars that we are conducting for the Hipparcos space mission and its possible contribution to a long-term planet search program.Type of Medium: Electronic ResourceURL: -

ISSN: 1572-946XSource: Springer Online Journal Archives 1860-2000Topics: PhysicsNotes: Abstract The National Radio Astronomy Observatory's proposed Millimeter Array (MMA) will bring unprecedented sensitivity, angular resolution, and image dynamic range to the millimeter wavelength region of the spectrum. An obvious question is whether such an instrument could be used to detect planets orbiting nearby stars. The techniques of aperture synthesis imaging developed for centimeter wavelength radio arrays are capable of producing images whose dynamic ranges greatly exceed the brightness ratio of a solar-type star and a Jupiter-like planet at sub-millimeter or millimeter wavelengths. The angular resolution required to separate a star and planet at a few pc distance can be obtained with baselines of several km. The greatest challenge is sensitivity. At the highest possible observing frequencies (∼ 300 GHz for typical high, dry sites, and ∼ 900 GHz from the Antarctic plateau), the proposed MMA will be unable to detect the thermal emission from a Jupiter-like planet a few pc away. An upgraded MMA operating near 300 GHz with twice the currently proposed number of antennas, a 20% fractional bandwidth, and improved receivers could detect Jupiter at 4 pc in a few months. Building such an array on the Antarctic plateau and operating at ≈ 900 GHz would allow Jupiter at 4 pc to be detected in approximately one day of observing time.Type of Medium: Electronic ResourceURL: -

ISSN: 0003-276XKeywords: Life and Medical Sciences ; Cell & Developmental BiologySource: Wiley InterScience Backfile Collection 1832-2000Topics: MedicineNotes: The dorsal epidermis of fetal and newborn rats was examined to determine the difference in ability of the basal cells to bind tritiated thymidine during different stages of epidermal morphogenesis. Five rats were examined for each time period from the eleventh day of gestation to the fifth day after birth. The number of labeled cells in 5000 basal cells was counted and expressed as a percentage. The labeling index is ∼ 10% from the eleventh to the fifteenth fetal day. It increases to ∼ 30% by the eighteenth day, decreases to ∼ 10% from the twenty-first day until the first postpartum day and drops to 5% or less from the second to fifth day. These changes in labeling index are accompanied by and apparently correlated with the normal differentiation of rat epidermis. The growth of the epidermis is continuous during the course of the study. Keratohyalin granules begin to form on the eighteenth day and by the twentieth day the first cornified cells appear. The s. corneum becomes progressively thicker each day thereafter. The s. Malpighii, on the other hand, decreases somewhat in thickness after birth. The labeling index curve represents a relationship between basal cell activity and control or influencing mechanisms inherent in the maturational system of skin. The increase and decrease are not related to growth alone, but appear to be related to differentiation.Additional Material: 11 Ill.Type of Medium: Electronic ResourceURL:
