Classical Be Stars
- J. Porter, T. Rivinius
- Physics
- 1 October 2003
Recent results for classical Be stars are reviewed and links to general astrophysics are presented. Classical Be stars are B-type stars close to the main sequence that exhibit line emission over the… Expand
On the binarity of Herbig Ae/Be stars
- D. Baines, R. Oudmaijer, J. Porter, M. Pozzo
- Physics
- 21 December 2005
We present high-resolution spectro-astrometry of a sample of 28 Herbig Ae/Be and three F-type pre-main-sequence stars. The spectro-astrometry, which is essentially the study of unresolved features in… Expand
Triggered massive star formation in the vicinity of WR 48a
We utilise Midcourse Space Experiment mid-IR imaging and published data to discuss the (massive) star formation region at galactic longitude ∼305 ◦ , apparently associated with the Wolf Rayet WR 48a… Expand
Phylogenetic Relationships in Euphorbieae (Euphorbiaceae) Based on ITS and ndhF Sequence Data
- V. Steinmann, J. Porter
- Biology
- 23 January 2002
The monophyly and phylogenetic relationships of the tribe Euphorbieae (Euphorbiaceae) were evaluated using separate weighted maximum parsimony analyses of nucleotide sequences of the nrDNA internal… Expand
Phylogeny of Opuntioideae (Cactaceae)
- M. Griffith, J. Porter
- Biology
- International Journal of Plant Sciences
- 1 January 2009
Opuntioideae are a diverse subfamily of Cactaceae with significant diversity of form and habitat and wide distribution throughout the New World. Nuclear ribosomal ITS and chloroplast trnL‐trnF region… Expand
The circumstellar envelopes of Be stars: viscous disc dynamics
- C. Jones, T. A. A. Sigut, J. Porter
- Physics
- 1 June 2008
We have constructed models of axisymmetric, circumstellar envelopes for Be star discs by successfully combining two numerical codes: a non-local thermodynamic equilibrium (non-LTE) radiative transfer… Expand
A Phylogenetic Classification of Polemoniaceae
- J. Porter, L. Johnson
- Biology
- 2000
Three hundred seventy nine species of Polemoniaceae are arranged in a phylogenetic classificat ion composed of three subfamilies, eight tribes. and 26 genera. Nomenclature of one tribe is clarified… Expand
