Images solar observatory peel away layers stellar mystery
2019/11/22
NSF-funded scientists at the New Jersey Institute of Technology have shed new light on one of the central mysteries of solar physics: how energy from the sun is transferred to the star's upper atmosph...
Organizers of SABID 2017 workshop solicit high-quality original research papers in the closely related areas of solar and stellar astronomy big data. Innovative data mining techniques in these fields ...
Using Kepler transit observations to measure stellar spot belt migration rates
Activity Spots Planetary Systems Planet Satellites Sunspots
2012/2/23
Planetary transits provide a unique opportunity to investigate the surface distributions of star spots. Our aim is to determine if, with continuous observation (such as the data that will be provided ...
The unusual vertical mass distribution of NGC 4013 seen through the Spitzer Survey of Stellar Structure in Galaxies (S4G)
Spitzer Survey Stellar Structure Galaxies (S4G)
2011/9/27
NGC 4013 is a nearby Sb edge-on galaxy known for its "prodigious" HI warp and its "giant" tidal stream. Previous work on this unusual object shows that it cannot be fitted satisfactorily by a canonica...
The 55 Cancri System: Fundamental Stellar Parameters, Habitable Zone Planet, and Super-Earth Diameter
Cancri System: Fundamental Stellar Parameters Super-Earth Diameter
2011/9/30
The bright star 55 Cancri is known to host five planets, including a transiting super-Earth. We use the CHARA Array to directly determine the following of 55 Cnc's stellar astrophysical parameters: $R...
Stripping a debris disk by close stellar encounters in an open stellar cluster
Stars : circumstellar matter surveys stars: low-mass planetary systems : formation
2011/9/28
A debris disk is a constituent of any planetary system surrounding a main sequence star. We study whether close stellar encounters can disrupt and strip a debris disk of its planetesimals in the expan...

Excitation of Solar-like Oscillations：From PMS to MS Stellar Models
Turbulence convection oscillations excitation sun stars:α Cen A—stars:main and pre-main sequence stars
2009/5/12
The amplitude of solar-like oscillations results from a balance
between excitation and damping. As in the sun, the excitation is attributed
to turbulent motions that stochastically excite the p mode...
