4/30 Morley: From Exotic to Familiar: Observing Exoplanet Atmospheres in the Coming Decade

Astrophysics Seminar Monday, April 30, 2018 3:30pm, CAS 502 From Exotic to Familiar: Observing Exoplanet Atmospheres in the Coming Decade Caroline Morley Harvard CfA Abstract: Observations of exoplanets to date have used the Hubble and Spitzer Space Telescopes to reveal exotic exoplanet atmospheres. Substantial resources have been dedicated to characterizing the handful of planets with […]

4/23 Lee: What Can Modeling Chemical Abundance Ratio Distributions in Dwarf Galaxies Tell Us?

Astrophysics Seminar Monday, April 23, 2018 3:30pm, CAS 502 What Can Modeling Chemical Abundance Ratio Distributions in Dwarf Galaxies Tell Us? Duane Lee MIT Kavli Institute Abstract: The chemical abundances found in stars convey a wealth of information on stellar evolution from stellar nucleosynthesis (e.g., stellar core burning, AGB phase burning, explosive supernova phase fusion, […]

4/26 Stapelfeldt: Extending our Vision to a Galaxy of Planets

Space Physics Seminar Thursday, April 26, 2018 3:30pm, CAS 502 Extending our Vision to a Galaxy of Planets Dr. Karl Stapelfeldt Jet Propulsion Laboratory, Caltech Abstract: The most obvious method of studying extrasolar planets ‐ directly imaging them alongside their parent star ‐ is also the most difficult. Image contrasts exceeding a billion to one, […]

4/17 Berger: Rattle and Shine: Joint Detection of Gravitational Waves and Light from the Binary Neutron Star Merger GW170817

Astrohysics Seminar Tuesday, April 17, 2018 3:30pm, CAS 502 Rattle and Shine: Joint Detection of Gravitational Waves and Light from the Binary Neutron Star Merger GW170817 Edo Berger Harvard CfA Abstract: The much‐anticipated joint detection of gravitational waves and electromagnetic radiation was achieved for the first time on August 17, 2017, for the binary neutron […]

4/05 Ray: Characterizing Jupiter’s Auroral Acceleration Region

Space Physics Seminar Friday, April 5, 2018 Characterizing Jupiter’s Auroral Acceleration Region Licia Ray University of Lancaster Abstract: At Jupiter and other magnetized planets, auroral emissions are signatures of particle acceleration above the planetary atmosphere. Juno is currently exploring Jupiter’s auroral acceleration region; however its low altitude coverage is limited to the dusk side of […]

3/26 Akiyama: Imaging and Filming Black Holes

Astrophysics Seminar Monday, March 26, 2018 Imaging and Filming Black Holes, with the Event Horizon Telescope. Kazunori Akiyama MIT-Haystack Abstract: Does the black hole appear as a literally dark object if we take its picture on scales of its event horizon? This simple and intriguing question will be observationally addressed by an Earth-sized radio interferometer […]

3/19 Arce: Shedding New Light on Star Formation

Astrophysics Seminar Monday, March 19, 2018 Shedding New Light on Star Formation, from Molecular Clouds to Disks. Héctor Arce Yale University Abstract: Star formation is a multi‐scale process. Star‐forming clouds in our galaxy have sizes of a few tens of parsecs. Dense condensations within clouds, where individual (or groups of) stars form, are smaller by […]

4/02 Hawkins: Galactic Archaelogy in the Gaia Era

Astrophysics Seminar Monday, April 2, 2018 Galactic Archaeology in the Gaia Era Keith Hawkins Columbia University Abstract: One of the key objectives of modern astrophysics is to understand the formation and evolution of galaxies. In this regard, the Milky Way is a fantastic testing ground for our theories of galaxy formation. However, dissecting the assembly […]
