Seismology and activity of the F type star HD 49933
A 10-night asteroseismic observation programme has been conducted in January 2004 with the spectrometer harps at the ES0 3.6-m telescope. The selected target, the 6th magnitude F5V star HD 49933, was chosen among the prime candidates of corot, the European space mission dedicated to characterize stellar oscillations mode with high precision photometry measurements. This star shows important lin...
متن کاملEccentric giant planets in open star clusters
The discovery of Jupiter–like planets with high eccentricities raises the question of how these eccentricities are produced. We propose that eccentric giant planets (EGPs) could be formed in open star clusters as a result of purely dynami-cal processes. It is found that at least 3% of the giant planets around stars in open clusters can develop high eccentricities due to multi-body gravitational...
متن کاملStar cluster disruption by giant molecular clouds
We investigate encounters between giant molecular clouds (GMCs) and star clusters. We propose a single expression for the energy gain of a cluster due to an encounter with a GMC, valid for all encounter distances and GMC properties. This relation is verified with N -body simulations of cluster-GMC encounters, where the GMC is represented by a moving analytical potential. Excellent agreement is ...
متن کاملGPS seismology
GPS seismology uses convential geodetic models to analyze GPS data at high sampling rates, such as 1 Hz. GPS seismology results are shown for the Denali, San Simeon, Tokachi-oki, and Chuetsu earthquakes. Records for these earthquakes indicate that GPS is an excellent instrument for measuring large displacements near earthquake ruptures. GPS systems can be improved for seismic applications if th...
متن کاملStatistical Seismology
Stochastic models with an increasing component of physical reasoning have been slowly gaining acceptance over the last two decades. The subject of statistical seismology aims to bridge the gap between physics-based models without statistics, and statistics-based models without physics. This volume, which is based largely on papers presented at the 3rd International Workshop on Statistical Seism...
