Statistics of Stellar Variability from Kepler - I: Revisiting Quarter 1 with an Astrophysically Robust Systematics Correction
We investigate the variability properties of main sequence stars in the first month of Kepler data, using a new astrophysically robust systematics correction. We find that the fraction of stars with variability greater than that of the Sun is 60%, which is marginally consistent with previous studies, and confirm the trend of increasing variability with decreasing effective temperatures. We defi...
متن کاملA Stellar Model-fitting Pipeline for Asteroseismic Data from the Kepler Mission
Over the past two decades, helioseismology has revolutionized our understanding of the interior structure and dynamics of the Sun. Asteroseismology will soon place this knowledge into a broader context by providing structural data for hundreds of Sun-like stars. Solar-like oscillations have already been detected from the ground in several stars, and NASA’s Kepler mission is poised to unleash a ...
متن کاملCommissioning of ATLAS Data Quality Infrastructure with First Collision Data
During particle physics data taking, the data being recorded must be monitored and checked continuously and promptly. The data quality system of the ATLAS experiment at the Large Hadron Collider provides the means to investigate and monitor the data recorded. Over the course of 2010, this system has been commissioned successfully with first collision data. Data quality monitoring enables prompt...
متن کاملHATnet VARIABILITY SURVEY IN THE HIGH STELLAR DENSITY ‘‘KEPLER FIELD’’ WITH MILLIMAGNITUDE IMAGE SUBTRACTION PHOTOMETRY
The Hungarian-made Automated Telescope Network (HATnet) is an ongoing project to detect transiting extrasolar planets using small-aperture (11 cm diameter) robotic telescopes. In this paper, we present the results from using image subtraction photometry to reduce a crowded stellar field observed with one of the HATnet telescopes (HAT-5). This field was chosen to overlap with the planned Kepler ...
متن کاملFirst thoughts
Abstract: Jean Mandler proposes an original and richly detailed theory of how concepts relate to sensory and motor capacities. I focus on her claims about conceptual representations and the processes that produce them. On her view, concepts are declarative representations of object kind information. First, I argue that since sensorimotor representations may be declarative, there is no bar to pe...
