Fishery science: the study of fishery systems

Charles, Anthony Trevor, 1956- (EDP Sciences, 1995)

The pursuit of sustainable fisheries requires a broad vision of fishery science - as the scientific study of fishery systems. This implies the incorporation into fishery science of research on fishery management, fishing ...

Modelling self-pollution of globular clusters from asymptotic giant branch stars

Fenner, Y.; Campbell, S.; Karakas, A. I.; Lattanzio, J. C.; Gibson, Brad K. (Royal Astronomical SocietyOxford University Press, 2004)

A self-consistent model of the chemical evolution of the globular cluster NGC 6752 is presented to test a popular theory that observed abundance anomalies are due to ‘internal pollution’ from intermediate-mass asymptotic ...
A proposed modification of the rate equations for reactions on grain surfaces

Casselli, P.; Hasegawa, T. I.; Herbst, Eric (American Astronomical Society and IOP Publishing, 1998-03-01)

The rate equations currently utilized for grain reactions in gas-grain chemical models of interstellar clouds are inappropriate under certain conditions because of the discrete nature of grain particles. Appropriate ...
Alignments of the dominant galaxies in poor clusters

Fuller, Todd M.; West, Michael J.; Bridges, Terry J. (American Astronomical SocietyIOP Science, 1999-07-01)

We have examined the orientations of brightest cluster galaxies (BCGs) in poor MKW (Morgan, Kayser, and White) and AWM (Albert, White, and Morgan) clusters and find that, like their counterparts in richer Abell clusters, ...

The Microvariability and Oscillations of STars (MOST ) photometric satellite observed three rotations of [epsilon] Eri continuously in late 2005. We detected two spots ([delta] m[approximately] 0.01) at different latitudes ...
Detection of solar-like oscillations in the red giant star [Epsilon] Ophiuchi by MOST spacebased photometry

Context. Solar-like oscillations have been discovered in a few red giants, including e Oph, through spectroscopy. Acoustic modes around 60 μHz were clearly seen in this star, but daily aliasing of the groundbased data ...
Weak magnetic fields in Ap/Bp stars: evidence for a dipole field lower limit and a tentative interpretation of the magnetic dichotomy

Auriere, M.; Wade, G. A.; Silvester, J.; Lignieres, F.; Bagnulo, S.; Bale, K.; Dintrans, B.; Donati, J. F.; Folsom, C. P.; Gruberbauer, Michael; Toque, N. (EDP Sciences, 2007-12)

Aims. We investigated a sample of 28 well-known spectroscopically-identified magnetic Ap/Bp stars, with weak, poorly-determined or previously undetected magnetic fields. The aim of this study is to explore the weak part ...
Properties of simulated Milky Way-mass galaxies in loose group and field environments

Few, C. G.; Gibson, Brad K.; Courty, S.; Michel-Dansac, L.; Brook, C. B.; Stinson, G. S. (EDP Sciences, 2012-11)

Aims. We test the validity of comparing simulated field disk galaxies with the empirical properties of systems situated within environments more comparable to loose groups, including the Milky Way’s Local Group. Methods. ...
Oscillation mode linewidths of main-sequence and subgiant stars observed by Kepler

Appourchaux, T.; Benomar, O.; Gruberbauer, Michael; Chaplin, W. J.; Garcia, R. A.; Handberg, R.; Verner, G. A.; Antia, H. M.; Campante, T. L.; Davies, G. R. (EDP Sciences, 2012-01)

Context. Solar-like oscillations have been observed by Kepler and CoRoT in several solar-type stars. Aims. We study the variations in the stellar p-mode linewidth as a function of effective temperature. Methods. We study ...
UBV photometry of the open clusters NGC 6604 and NGC 6704

Forbes, Doug; DuPuy, David L. (American Astronomical Society, 1978-03)

The open clusters NGC 6604 and NGC 6704 have been studied with UBV photoelectric and photographic photometry, resulting in improved distance and color-magnitude diagrams. NGC 6604 is a very young (~4x 10 [supercript 6] yr) ...
Non-detection of previously reported transits of HD 97658b with MOST photometry

Dragomir, Diana; Matthews, Jaymie M.; Howard, Andrew W.; Antoci, Victoria; Henry, Gregory W.; Guenther, David B.; Johnson, John A.; Kuschnig, Rainer; Marcy, Geoffrey W.; Moffat, Anthony F. J. (American Astronomical Society, 2012-11-10)

The radial velocity-discovered exoplanet HD 97658b was recently announced to transit, with a derived planetary radius of 2.93 ± 0.28 R⊕. As a transiting super-Earth orbiting a bright star, this planet would make an attractive ...
