Download or read book Exploring the Extremes of Exoplanet Detection and Characterization in High-magnification Microlensing Events written by Jennifer C. Yee. This book was released on 2013. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The field of microlensing planet searches is about to enter a new phase in which wide-field surveys will be the dominant mode of planet detection. In addition, there are now plans to execute microlensing surveys from space allowing the technique to reach smaller planets and resolve some of difficulties of ground-based microlensing where the resolution is poor. This new phase of observations also requires a new mode of analysis in which events are analyzed en masse rather than as individuals.

Book Synopsis Measurement of Parallax and Lens Mass in the Gravitational Microlensing Free Floating Planet Event MOA-2011-BLG-274, and Aspects of Planet Detection at Moderately High Magnification by : Matthew Freeman

Download or read book Measurement of Parallax and Lens Mass in the Gravitational Microlensing Free Floating Planet Event MOA-2011-BLG-274, and Aspects of Planet Detection at Moderately High Magnification written by Matthew Freeman. This book was released on 2013. Available in PDF, EPUB and Kindle. Book excerpt: Microlensing is a powerful technique for detecting non-luminous objects in the galaxy. This has been one of several techniques that, in the past few years, have discovered hundreds of planets orbiting around other stars in our galaxy. The microlensing event MB11274 showed a short timescale and a large source size effect. These suggest that, rather than being a star, the lens body in this event may be a free floating planet, a class of object only recently discovered. A measurement of parallax in this event would allow the mass of this object to be measured - the first time that the mass of one of these planets has been measured directly. In this thesis an attempt to measure the terrestrial parallax signal in the event is described. Searches are also made for a nearby star, and any moons orbiting the planet. In addition, microlensing surveys looking for planets usually focus on the highest magnification events, as it is assumed that they give the best chance of detection. This thesis also presents analysis of moderate magnification microlensing events, which suggests that this type of event provides a higher sensitivity to planets.

Book Synopsis Exoplanet Science Strategy by : National Academies of Sciences, Engineering, and Medicine

Download or read book Exoplanet Science Strategy written by National Academies of Sciences, Engineering, and Medicine. This book was released on 2019-01-17. Available in PDF, EPUB and Kindle. Book excerpt: The past decade has delivered remarkable discoveries in the study of exoplanets. Hand-in-hand with these advances, a theoretical understanding of the myriad of processes that dictate the formation and evolution of planets has matured, spurred on by the avalanche of unexpected discoveries. Appreciation of the factors that make a planet hospitable to life has grown in sophistication, as has understanding of the context for biosignatures, the remotely detectable aspects of a planet's atmosphere or surface that reveal the presence of life. Exoplanet Science Strategy highlights strategic priorities for large, coordinated efforts that will support the scientific goals of the broad exoplanet science community. This report outlines a strategic plan that will answer lingering questions through a combination of large, ambitious community-supported efforts and support for diverse, creative, community-driven investigator research.
