Searching for transit timing variations in transiting exoplanet systems
Marie Hrudková, Ian Skillen, Chris Benn +5
Searching for transit timing variations in the known transiting exoplanet systems can reveal the presence of other bodies in the system. Here we report such searches for two transi…
The FERRUM Project: experimental and theoretical transition rates of forbidden [Sc II] lines and radiative lifetimes of metastable Sc II levels
H. Hartman, J. Gurell, P. Lundin +6
Context. In many plasmas, long-lived metastable atomic levels are depopulated by collisions (quenched) before they decay radiatively. In low-density regions, however, the low colli…
The VLT-FLAMES survey of massive stars: Evolution of surface N abundances and effective temperature scales in the Galaxy and Magellanic Clouds
C. Trundle, P. L. Dufton, I. Hunter +4
We present an analysis of high resolution VLT-FLAMES spectra of 61 B-type stars with relatively narrow-lined spectra located in 4 fields centered on the Milky Way clusters; NGC3293…
Proof of polar ejection fom the close-binary core of the planetary nebula Abell 63
Deborah L. Mitchell, Don Pollacco, T. J. O'Brien +4
We present the first detailed kinematical analysis of the planetary nebula Abell 63, which is known to contain the eclipsing close-binary nucleus UU Sge. Abell 63 provides an impor…
Understanding B-type supergiants in the low metallicity environment of the SMC II
C. Trundle, D. J. Lennon
Despite a resurgence of effort over the last decade in the area of massive stars there is still ambiguity over their evolutionary path, contamination of their surface abundances an…
Understanding B-type Supergiants in the Low Metallicity Environment of the SMC
C. Trundle, D. J. Lennon, J. Puls +1
Spectroscopic analyses of 7 SMC B-type supergiants and 1 giant have been undertaken using high resolution optical data obtained on the VLT with UVES. FASTWIND, a non-LTE, spherical…
