Proposed by the National Surgical Adjuvant Breast and Bowel Project (NSABP) in Pittsburgh, Pennsylvania, the STELLAR (Study to Evaluate Letrozole and Raloxifene) trial would have tested the drug letrozole against an older drug in 12,800 postmenopausal women at high risk for breast cancer.
In the Comparison of the Efficacy and Safety of Rosuvastatin Versus Atorvastatin, Simvastatin, and Pravastatin Across Doses (STELLAR) study, across-dose comparisons showed that, in patients with LDL-C levels of 160 250 mg/dL and triglyceride levels <400 mg/dL, rosuvastatin 10 80 mg/d reduced LDL-C levels by a mean of 8.2% more than did atorvastatin 10 80 mg/d (P<0.001).
These conclusions are in agreement with the CURVES and the STELLAR studies, in which atorvastatin and rosuvastatin, respectively, showed similar effects as other statin [7], [8].
Evidence that Neptune has one or more rings arose in the mid-1980s when stellar occultation studies from Earth occasionally showed a brief dip in the star's brightness just before or after the planet passed in front of it.
The applications cover classical up to relativistic MHD simulations, of particular relevance for astrophysical magnetized jet and stellar wind studies.
Typical examples of studies that focused on the three-body dynamics include Ford et al. (2000), Fabrycky and Tremaine (2007), Naoz et al. (2013), Naoz and Fabrycky (2014), Liu et al. (2015a), and stellar evolution studies include Eggleton and Kiseleva (1996), Iben and Tutukov (1999), Kuranov et al. (2001).
Excluding close-in planets that have lost their gas envelope due to stellar irradiation, studies of the metallicity of stars suggest a dividing line of 1.7 Earth radii between rocky planets and gas dwarfs; then another dividing line at 3.9 Earth radii between gas dwarfs and gas giants.
Most stars (including the sun) go through a variable stage, so they are used to study stellar life-cycles, among other things.
Just as seismologists employ earthquakes to probe our planet's mantle and core, so astronomers use these so-called asteroseismological vibrations to study stellar interiors.
He stayed on to earn a cum laude distinction for his master's thesis and complete a Ph.D. on the interior structure of stars, and now he works at the South African Astronomical Observatory in Sutherland, where he continues to study stellar interiors.
Take stellar notes to study from.
