Exempel på stellar

• The enhanced activity revealed itself in the form of strong highenergy emissions, frequent flares and a powerful stellar wind.

• The diamond represents the stellar position (the star itself is not detected as submillimetre observations are not sensitive to hot compact objects).

• Updated electron-conduction opacities: the impact on low-mass stellar models.

• Additional applications for these results are in astrophysical and planetary interaction of meteoritic materials with high-density radiation fields such as those generated in near-stellar regions.

• The ultimate cause of the inward motion is the stellar gravitational potential.

• The stellar mass and metallicity, and the initial values of luminosity, effective temperature, core temperature and core pressure were individually set.

• Stars known to have exoplanetary systems are then compared to their nearest matching stellar type within this framework.

• Stellar distances and luminosities were calculated using the above data and procedures described in the text.

• The luminosity evolution of the main-sequence central star is deduced by polynomial fitting of stellar evolution models.

• In our study we discuss one possible existence of counter-rotation in the scale of a planetary system, most probably caused by a stellar flyby.

• Refreshingly, they do not claim stellar performance, nor that automatic speech recognition has been solved by their work.

• The cast of authors is stellar - many of the papers contain superb work.

• The model is based on the global carbon cycle mediated by life and driven by increasing stellar luminosity and plate tectonics.

• Such planets are expected to occupy the outer regions of their habitable zones where stellar flux and effective temperatures are lower.

• Chapter 8 moves to the stars, introducing the basics of stellar astrophysics and considers what stars might be suitable for supporting life.
