Lowell Observatory Director Eileen Friel has been selected as an AAAS Fellow for her contributions to the astronomical community. She is recognized for her diligence in mentoring young scientists through the Research Experiences for Undergraduates program.
This issue features studies on variability in NGC2301 II, superhumps in cataclysmic binaries, and host galaxies of QSOs at high redshift. Researchers also investigate data exchange standards for optical interferometry and analyze seeing data for the Advanced Technology Solar Telescope.
Researchers have developed a new model to predict the physics of stellar burning, particularly in stars like V4334 Sgr that undergo brief rebirths. The model predicts that V4334 Sgr will become much hotter and then slowly repeat the stellar rebirth cycle, returning to its current temperature in roughly two hundred years.
Astrophysicist James Annis suggests that cataclysmic gamma-ray bursts could be sterilizing galaxies, preventing extraterrestrial life from reaching Earth. This theory may provide an explanation for the Fermi Paradox, with intelligent life having recently emerged in the Galaxy and being unable to explore yet.
A team of astronomers led by Bo Reipurth and John Bally observed that ultraviolet radiation from nearby massive stars destroyed the cocoons of gas and dust surrounding young stars, revealing billions of miles long supersonic jets. The destruction has provided new insight into star birth and evolution, and may have implications for the ...
