Autor: Lawrie K. Brown, Magdalena Blanz, Joanne Russell, Timothy S. George, Peter Martin, Sidsel Birkelund Schmidt, John Wishart, B. Dieterich

Publikováno v: Nutrient Cycling in Agroecosystems. 118:149-163

Traditional crofting in Scotland used Bere barley fertilised with seaweed. Bere has known abilities to cope with the marginal, high pH soils without inorganic fertiliser addition. The objective of this study was to assess whether Bere productivity is

Extending the life of the Cosmic Origins Spectrograph (COS) with new lifetime positions

Publikováno v: UV, X-Ray, and Gamma-Ray Space Instrumentation for Astronomy XXII.

Since its installation on the Hubble Space Telescope in 2009, the Cosmic Origins Spectrograph (COS) has obtained thousands of spectra in the ultraviolet. Most of these observations have used the far ultraviolet (FUV) channel. The microchannel plates

The Solar Neighborhood XLVII: Comparing M Dwarf Models with Hubble Space Telescope Dynamical Masses and Spectroscopy

Autor: Serge B. Dieterich, Todd J. Henry, Wei-Chun Jao, Andrew Simler

We use HST/STIS optical spectroscopy of ten M dwarfs in five closely separated binary systems to test models of M dwarf structure and evolution. Individual dynamical masses ranging from 0.083 to 0.405 Mo for all stars are known from previous work. We

The Solar Neighborhood. XLVI. Revealing New M Dwarf Binaries and their Orbital Architectures

Autor: Eliot Halley Vrijmoet, Todd J. Henry, Serge B. Dieterich, Wei-Chun Jao

We use 20 years of astrometric data from the RECONS program on the CTIO/SMARTS 0.9-m to provide new insight into multiple star systems in the solar neighborhood. We provide new and updated parallaxes for 210 systems and derive nine high-quality astro

Dynamical Masses of Eps Ind B and C: Two Massive Brown Dwarfs at the Edge of the Stellar-Substellar Boundary

Autor: Wei-Chun Jao, Maggie A. Thompson, Alan P. Boss, Sergio B. Dieterich, Alycia J. Weinberger, Jonathan Gagné, Tri L. Astraatmadja, Todd J. Henry, Guillem Anglada-Escudé

We report individual dynamical masses for the brown dwarfs Epsilon Indi B and C, which have spectral types of T1.5 and T6, respectively, measured from astrometric orbit mapping. Our measurements are based on a joint analysis of astrometric data from

The Solar Neighborhood XLIV: RECONS Discoveries within 10 Parsecs

Autor: Sergio B. Dieterich, Charlie T. Finch, Wei-Chun Jao, Philip A. Ianna, John P. Subasavage, Adric R. Riedel, Todd J. Henry, E. H. Vrijmoet, Michele L. Silverstein, Jennifer G. Winters

We describe the 44 systems discovered to be within 10 parsecs of the Sun by the RECONS team, primarily via the long-term astrometry program at CTIO that began in 1999. The systems --- including 41 with red dwarf primaries, 2 white dwarfs, and 1 brown

We report the discovery of a new ultra-short-period planet and summarize the properties of all such planets for which the mass and radius have been measured. The new planet, K2-131b, was discovered in K2 Campaign 10. It has a radius of 1.81-0.12+0.16

The Solar Neighborhood XXXVII: The Mass-Luminosity Relation for Main Sequence M Dwarfs

We present a Mass-Luminosity Relation (MLR) for red dwarfs spanning a range of masses from 0.62 Msun to the end of the stellar main sequence at 0.08 Msun. The relation is based on 47 stars for which dynamical masses have been determined, primarily us

The extent of methane (CH4) emissions after fertilisation of grassland with digestate

Autor: B. Dieterich, P. Frost, Christoph Müller, S. Gilkinson, John Finnan

Publikováno v: Biology and Fertility of Soils. 48:981-985

Methane (CH4) emissions following surface application of liquid digestate were measured on agricultural grassland. The total extent of emissions was estimated by curve fitting and integration. The temporal pattern of the CH4 efflux was well described

Publikováno v: Nizami, A-S, Orozco, A, Groom, E, Dieterich, B & Murphy, J 2012, ' How much gas can we get from grass? ' Applied Energy, vol 92, pp. 783-790 ., 10.1016/j.apenergy.2011.08.033

Grass biomethane has been shown to be a sustainable gaseous transport biofuel, with a good energy balance, and significant potential for economic viability. Of issue for the designer is the variation in characteristics of the grass depending on locat
