Ever wonder how sunspots are formed? This paper takes a close look at how the magnetic structures that give rise to sunspots make it all the way from the deep solar interior to its surface. Continue reading
Stellar variability has received more attention recently due to the problems it poses in the detection of exoplanets; however the study of variability is a field of its own. What causes activity? How does magnetic activity vary with different stars? This paper looks at results from the CoRoT satellite (for Convection, Rotation and planetary Transits), which was launched in December of 2006. This paper is concerned with the long-term photometric microvariability of stars and how stellar activity relates to rotation period and temperature. Continue reading
My first AAS is at a close. On Tuesday, I attended still more talks on exoplanets, some of which I will discuss below, while on Wednesday I manned my poster. Continue reading
Understanding the uncertainties involved in the techniques used to detect exoplanets is an important aspect of the search for life beyond the Earth. What role could phenomenon like sunspots play in planet detection? Continue reading
