The Li Overabundance of J37: Diffusion or Accretion? (2004)
Presentation / Conference Contribution
F. Ashwell, J., Jeffries, R. D., Smalley, B., P. Deliyannis, C., Steinhauer, A., & R. King, J. The Li Overabundance of J37: Diffusion or Accretion?. Presented at Proceedings of the International Astronomical Union

In September 2002 the discovery of a super Li-rich F-dwarf (J37) in NGC 6633, an iron poor analogue of the better studied Hyades and Praecepe open clusters, was announced. This unique star was thought to be the smoking gun for the action of diffusion... Read More about The Li Overabundance of J37: Diffusion or Accretion?.

Mid-infrared observations of young stellar objects in the vicinity of sigma Orionis (2004)
Journal Article
Oliveira, J. M., & van Loon, J. T. (2004). Mid-infrared observations of young stellar objects in the vicinity of sigma Orionis. Astronomy & Astrophysics, 418(2), https://doi.org/10.1051/0004-6361%3A20034518

We present new mid-infrared observations of objects in the vicinity of the O-star sigma Orionis, obtained with TIMMI-2 at ESO. By constraining their near- and mid-infrared spectral energy distributions, we established the nature of previously known I...

Eclipsing binaries in open clusters (2003)
Presentation / Conference Contribution
Southworth, J., Maxted, P., & Smalley, B. Eclipsing binaries in open clusters

Accurate physical parameters have been determined for two early-type detached eclipsing binaries in the open cluster h Persei (NGC 869). Masses accurate to 1.5% are derived from high-resolution spectroscopy and radii accurate to 4--6% have been obtai... Read More about Eclipsing binaries in open clusters.

Understanding the chemistry of hydroxyaluminosilicates: from the mechanism of formation to the determination of an equilibrium constant (2003)
Thesis
Schneider, C. Understanding the chemistry of hydroxyaluminosilicates: from the mechanism of formation to the determination of an equilibrium constant. (Thesis). Keele University. https://keele-repository.worktribe.com/output/1080246

The proposition in recent years that silicic acid (Si(OH)4) acts as an environmental control of the biological availability of aluminium (Al) has presented inorganic chemistry with an intriguing scientific challenge. Si(OH)4 reacts with Al to form hy... Read More about Understanding the chemistry of hydroxyaluminosilicates: from the mechanism of formation to the determination of an equilibrium constant.

The use of vertical radar profiling (VRP) in GPR survey of ancient sedimentary strata (2003)
Book Chapter
Pringle, J., Westerman, A., Clark, J., Guest, J., Ferguson, R., & Gardiner, A. (2003). The use of vertical radar profiling (VRP) in GPR survey of ancient sedimentary strata. In Ground Penetrating Radar in Sediments (225 - 246). (Volume 211). The Geological Society. https://doi.org/10.1144/GSL.SP.2001.211.01.19

Vertical radar profiling (VRP) is an application of ground penetrating radar (GPR) technologies that can extract important subsurface information from suitable outcrops. Using standard GPR equipment, a site-specific time-depth calibration can be obta... Read More about The use of vertical radar profiling (VRP) in GPR survey of ancient sedimentary strata.

On the anomaly of Balmer line profiles of A-type stars. Fundamental binary systems (2002)
Journal Article
Smalley, B., B. Gardiner, R., Kupka, F., & S. Bessell, M. (2002). On the anomaly of Balmer line profiles of A-type stars. Fundamental binary systems. Astronomy & Astrophysics, 395(2), https://doi.org/10.1051/0004-6361%3A20021330

In previous work, Gardiner et al. (1999) found evidence for a discrepancy between the Teff obtained from Balmer lines with that from photometry and fundamental values for A-type stars. An investigation into this anomaly is presented using Balmer line... Read More about On the anomaly of Balmer line profiles of A-type stars. Fundamental binary systems.

No disks around low-mass stars and brown dwarfs in the young sigma Orionis cluster? (2002)
Journal Article
Oliveira, J., Jeffries, R., Kenyon, M., Thompson, S., & Naylor, T. (2002). No disks around low-mass stars and brown dwarfs in the young sigma Orionis cluster?. Astronomy & Astrophysics, https://doi.org/10.1051/0004-6361%3A20011778

We report on the analysis of 2MASS near-infrared data of a sample of low-mass stars and brown dwarfs in the sigma Orionis cluster. Youth and cluster membership have been spectroscopically confirmed using the Li I spectral line. We find little evidenc...

Rotation, activity and lithium in NGC 6475 (1997)
Journal Article
James, D. J., & Jeffries, R. D. (1997). Rotation, activity and lithium in NGC 6475. Monthly Notices of the Royal Astronomical Society, 292(2), 252–272. https://doi.org/10.1093/mnras/292.2.252

Radial and rotational velocities, chromospheric activity and lithium abundances are presented for an X-ray-selected sample of stars in the young (220 Myr) open cluster NGC 6475. Low-mass members of the cluster have been identified on the basis of pho... Read More about Rotation, activity and lithium in NGC 6475.
