The Blue Companion of 3C 65: A Star-forming Galaxy with a Probable Redshift of 2.8

DOI: 10.1086/305430 Bibcode: 1998ApJ...496..803C

Charlot, Stéphane; Dunlop, J. S.; Owen, Frazer +2 more

We present BVRIK images and photometry of the z = 1.175 radio galaxy 3C 65 and its extended blue companion, along with a 6 cm radio map. These data are used to test the hypotheses that the companion is scattering the continuum of a hidden active nucleus within the radio galaxy and/or is undergoing a starburst triggered by interaction with its radi…

Jovian and terrestrial low-frequency radio bursts: Possible cause of anomalous continuum

DOI: 10.1029/97JE03369 Bibcode: 1998JGR...10319993K

Kaiser, M. L.

Observations by the Ulysses Unified Radio and Plasma Wave instrument show that the most intense portion of the Jovian continuum emission appears to emanate from the planet's bow shock or magnetosheath region. This intense component is highly correlated with the Jovian ``type III'' or quasi-periodic (QP-15 and QP-40) bursts. I suggest that this int…

Lithium Abundance in Pop.II Stars A post-HIPPARCOS discussion

Bibcode: 1998SSRv...84..155S

Spite, M.; Hill, V.; Spite, F.

The relation between the lithium abundance observed in Population II stars and the primordial abundance, is still an open question (see Cayrel and Duncan, this meeting). A few recent results are discussed. HIPPARCOS data show that the standard model of stellar evolution can explain the 6Li detection in HD 84937, suggesting a negligible depletion o…

Surface photometry of early-type galaxies in the Hubble deep field

DOI: 10.1051/aas:1998206 Bibcode: 1998A&AS..129..583F

Fasano, G.; Filippi, M.

The detailed surface photometry of a sample of early-type galaxies in the Hubble Deep Field is presented as part of a long-term project aimed to settle strong observational constraints to the theories modelling the evolution of elliptical galaxies from the early stages. The sample has been extracted, in the V₆₀₆ band, from the database …

New Observations Testing the Adopted HIPPARCOS Link to the International Celestial Reference Frame

DOI: 10.1086/311654 Bibcode: 1998ApJ...506L..93S

Stone, Ronald C.

This paper tests the Hipparcos link to the extragalactic reference frame by using new data obtained after the release of the catalog, thereby providing an external check on the accuracy of the established link process. The new data consist of 689 positions of Hipparcos stars determined in the International Celestial Reference Frame (ICRF) from CCD…

Beta Cephei type variability in the ultraviolet spectrum and radial velocity of PHL 346

DOI: 10.1046/j.1365-8711.1998.01543.x Bibcode: 1998MNRAS.297..565D

Dufton, P. L.; van Leeuwen, F.; Keenan, F. P. +4 more

International Ultraviolet Explorer low-resolution and optical moderate-resolution spectra are presented for the high galactic latitude beta Cephei type star, PHL 346. Variability is identified in both the ultraviolet flux and the radial velocity with periods and phases consistent with those previously deduced from optical photometry. The similarit…

Constraints on Ultraviolet Absorption in the Intracluster Medium of Abell 1030

DOI: 10.1086/306417 Bibcode: 1998ApJ...508..608K

Koekemoer, Anton M.; Baum, Stefi A.; O'Dea, Christopher P. +3 more

We present results from an extensive Hubble Space Telescope (HST) spectroscopic search for UV absorption lines in the spectrum of the quasar B2 1028+313, which is associated with the central dominant galaxy in the cluster Abell 1030 (z = 0.178). This is one of the brightest known UV continuum sources located in a cluster and therefore provides an …
