Asteroseismology of Sun-like Stars
In the past decade, helioseismology has revolutionized our understanding of the interior structure of the Sun. In the next decade, asteroseismology will place this knowledge into context, by providing structural information for dozens of pulsating stars across the H-R diagram. Solar-like oscillations have already been detected from the ground in a few stars, and several current and planned sate...
متن کاملProperties of Sun-like Stars with Planets
Planets have been reported orbiting the Sun-like stars 1 Cnc, Boo o, and And based on low-amplitude radial velocity variations. We have derived 1 Based on observations made at Mount Wilson Observatory, operated by the Mount Wilson Institute under an agreement with the Carnegie Institution of Washington. information on the rst two stars from analysis of spectra, as well as parallel records of hi...
متن کاملSpot Sizes on Sun-like Stars
The total area coverage by starspots is of interest for a variety of reasons, but direct techniques only provide estimates of this important quantity. Sunspot areas exhibit a lognormal size distribution irrespective of the phase of the activity cycle, implying that most sunspots are small. Here we explore the consequences if starspot areas were similarly distributed. The solar data allow for an...

متن کاملGrand challenges in the physics of the sun and sun-like stars
1. INTRODUCTION " If the Sun had no magnetic field, it would be as uninteresting as most astronomers think it is. " This statement is attributed to R. B. Leighton (Moore and Rabin, 1985). Personally I think the Sun is of enormous interest in all respects, magnetic and non-magnetic; nonetheless, the grand challenges I have selected for this article do indeed pertain to the Sun's magnetic field. ...
