Yields of rotating stars at solar metallicity (2004)
Journal Article
Hirschi, R., Meynet, G., & Maeder, A. Yields of rotating stars at solar metallicity. https://doi.org/10.1051/0004-6361%3A20041554. Manuscript submitted for publication

We present a new set of stellar yields obtained from rotating stellar models at solar metallicity covering the massive star range (12-60 solar masses). The stellar models were calculated with the latest version of the Geneva stellar evolution code de... Read More about Yields of rotating stars at solar metallicity.

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.

Accelerator mass spectrometry at the 4 MV Dynamitron Tandem in Bochum (2004)
Journal Article
(2004). Accelerator mass spectrometry at the 4 MV Dynamitron Tandem in Bochum. Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 255 - 260. https://doi.org/10.1016/j.nimb.2004.02.009

A feasibility test for Accelerator Mass Spectrometry has been carried out successfully at the 4 MV Dynamitron Tandem Laboratory in Bochum in conjunction with a new recoil separator. We describe the facility as well as results concerning the reproduci... Read More about Accelerator mass spectrometry at the 4 MV Dynamitron Tandem in Bochum.

Some updates on the role of magnetic fields in cataclysmic variables (2004)
Journal Article
Hellier, C. (2004). Some updates on the role of magnetic fields in cataclysmic variables

In this review talk I cover some recent developments in understanding the role that magnetic fields play in cataclysmic variables. I discuss the recent DNO--QPO unification models; the disk--magnetosphere boundary; some issues concerning the soft bla...

An L'-band survey for circumstellar discs around low-mass stars in the young σ Orionis cluster (2004)
Journal Article
Jeffries, R., Oliveira, J., & Van Loon, J. (2004). An L'-band survey for circumstellar discs around low-mass stars in the young σ Orionis cluster. Monthly Notices of the Royal Astronomical Society, 347(4), 1327 -1336. https://doi.org/10.1111/j.1365-2966.2004.07315.x

We present new K- and L'-band imaging of a representative sample of members of the young 3-5 Myr old sigma Orionis cluster. We identified objects with (K-L') excess by analysing colour-colour diagrams and comparing the observations with empirical mai...
