Using Balmer line profiles to investigate convection in A and F stars (2004)
Journal Article
Smalley, B., & Kupka, F. (2004). Using Balmer line profiles to investigate convection in A and F stars. Proceedings of the International Astronomical Union,

Balmer lines are an important diagnostic of stellar atmospheric structure, since they are formed at a wide range of depths within the atmosphere. The different Balmer lines are formed at slightly different depths making them useful atmospheric diagno... Read More about Using Balmer line profiles to investigate convection in A and F stars.

Model atmosphere analyses of post-common envelope stars (2004)
Journal Article
T. Rushton, M., Smalley, B., N. Ogley, R., H. Wood, J., H. Hauschildt, P., & N. Bleach, J. (2004). Model atmosphere analyses of post-common envelope stars. Proceedings of the International Astronomical Union,

Understanding post-common-envelope evolution is important in the studies of close-binary systems. The majority of all interacting binaries with a compact object in their system (e.g. cataclysmic variables, X-ray binaries) are thought to have passed t...

The ASTRA Spectrophotometer: A July 2004 Progress Report (2004)
Journal Article
Pazder, J., J. Adelman, S., Younger, P., F. Gulliver, A., Boyd, L., Epand, D., …Smalley, B. The ASTRA Spectrophotometer: A July 2004 Progress Report. https://doi.org/10.1017/S1743921305009968. Manuscript submitted for publication

A cross-dispersed spectrophotometer with CCD detector and its automated 0.5-m telescope at the Fairborn Observatory, now under construction, should begin observations in 6 to 9 months. The Citadel ASTRA Telescope will be able to observe Vega the prim... Read More about The ASTRA Spectrophotometer: A July 2004 Progress Report.

Observations of convection in A-type stars (2004)
Journal Article
Smalley, B. Observations of convection in A-type stars. https://doi.org/10.1017/S1743921304004478. Manuscript submitted for publication

Convection and turbulence in stellar atmospheres have a significant effect on the emergent flux from A-type stars. The recent theoretical advancements in convection modelling have proved a challenge to the observers to obtain measurements with suffic... Read More about Observations of convection in A-type stars.

Accurate fundamental parameters of eclipsing binary stars (2004)
Journal Article
Southworth, J., Smalley, B., Maxted, P., & Etzel, P. (2004). Accurate fundamental parameters of eclipsing binary stars. Proceedings of the International Astronomical Union, 2004(IAUS224), 548-561. https://doi.org/10.1017/S1743921305009324

The study of detached eclipsing binaries is one of the most powerful ways to investigate the properties of individual stars and stellar systems. We present preliminary masses, radii and effective temperatures for the eclipsing binary WW Aurigae, whic... Read More about Accurate fundamental parameters of eclipsing binary stars.

The Li Overabundance of J37: Diffusion or Accretion? (2004)
Journal Article
F. Ashwell, J., Jeffries, R. D., Smalley, B., P. Deliyannis, C., Steinhauer, A., & R. King, J. (2004). The Li Overabundance of J37: Diffusion or Accretion?. Proceedings of the International Astronomical Union, 2004(IAUS224), https://doi.org/10.1017/S1743921305009385

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?.
