(1994-04-18)The simplest interaction between sound and quantized superfluid vortices is investigated both analytically in the Born approximation and numerically, using the nonlinear Schrodinger equation. Compared with the scattering ...
-
(1994-06-10)Optical and spectrophotometric ata, gathered in the 1987-1994 interval, are presented for the planetary nebula N66 (WS 35 or SMP 83) in the Large Magellanic Cloud. These data show that the central star has suffered dramatic ...
-
(1994-07-01)We present H92alpha radio recombination line and radio continuum observations toward three cometary-like H II regions, G13.87 + 0.28, G32.80 + 0.19B, and G61.48 + 0.09B1, with an angular resolution of approximately 2''. ...
-
(UNIV CHICAGO PRESS, 1994-07-20)At angular resolution of approximately 1 arc second(s) the Cepheus A East Radio source is known to consist of 16 compact components clustered within a 25 arc second(s) radius region, most of which are aligned in stringlike ...
-
(UNIV CHICAGO PRESS, 1994-09-01)We have used observations gathered at CTIO to measure distances by the expanding photosphere method (EPM) to five Type II supernovae. These supernovae lie at redshifts from cz = 1100 km s-1 to cz - 5500 km s-1, and increase ...
-
(1994-11)We investigate the role of the full dynamical dependence of the free off-shell nucleon-nucleon t matrix on the optical potential for proton-nucleus elastic scattering in the 100—400 MeV incident energy range within a ...
-
(1994-12)We present spectroscopic and photometric data for SN 1992K, a Type Ia event found in the course of the Calan/Tololo supernova survey. These data show an impressive similarity with the spectra and light curves of the atypical ...
-
(1995)The crystal structure of the title phosphonium salt consists of a tetrahedral (C6Hs)P +C(C4HS)- (COOCH2CH3) cation and a Br- anion. The triphenylphosphonium group has P---C(phenyl) distances which are equal within ...
-
(1995-01)We have constructed Hubble diagrams in B and V for 13 Type Ia supernovae (SNe Ia) found in the course of the Calan/Tololo survey covering an unprecedented range in redshift (0.01 less than Z less than 0.1). As opposed to ...
-
(1995-03-01)Optical and UV spectrophotometric data for the planetary nebula N66 in the Large Magellanic Cloud gathered in the 1987-1994 interval are analyzed. The central star, which had a featureless weak continuum, has developed ...
-
(AMERICAN PHYSICAL SOC, 1995-07)We develop an approach for incorporating both medium and off-shell effects in the calculation of full-folding nucleon-nucleus optical potentials for elastic scattering. The approach is based on a flexible scheme for ...
-
(The American Astronomical Society, 1995-11-10)We present observations of the (J, K) = (2, 2) and (3, 3) inversion transitions of ammonia, made at ˜4" resolution with the VLA, in the direction of the G32.80 + 0.19 and G61.48 + 0.09 star-forming regions, which contain ...
-
(1996)A general theory for the spatial ordering of immobile clustered defects in irradiated materials is presented here. A vectorial form for the Fourier transforms of perturbations in the concentration of point and clustered ...
-
(1996-03-01)We present multifrequency, matching-beam, VLA radio continuum observations of the Cep A East radio source, known to consist of 16 compact ( 1") components clustered within a 25" radius region, most of which are aligned in ...
-
(1996-06)We present optical spectra from 3 to 21 days and lUE spectra at 10 and 19 days following the outburst of the extreme amplitude, very short orbital period cataclysmic variable AL Corn after a 20 yr quiescent interval. The ...
-
(American Astronomical Society, 1996-06)We study optical spectra in high and low activity states of the faint, distant Seyfert 1 galaxy C16.16. A strong stellar population contribution to the continuum is observed, even in the high-state spectrum. The low- ...
-
(The American Astronomical Society, 1996-07-20)The light curve of a distant Type Ia supernova acts like a clock that can be used to test the expansion of the universe. SN 1995K, at a spectroscopic redshift of z = 0.479, provides one of the first meaningful data sets ...
-
(1996-08)We present further results of fully-sampled observations in the J = 1!0 and J = 2!1 rotational transitions of 12CO and 13CO, obtained with the SEST telescope at 43 00 or 22 00 resolution, toward the Small Magellanic Cloud. ...
-
(UNIV CHICAGO PRESS., 1996-09-10)We model the dynamics of a fast, isothermal ionized stellar wind loaded with mass injected from photoevaporated globules surrounding the massive star. The effect of the mass injection is to produce a density profile such ...
