Julien’s primary interest and expertise lie in the field of data science where Math and Science are brought together to make sense of newly accessible pieces of Reality! Over the past five years, he has developed and applied new analysis techniques to map exoplanet atmospheres, study the radiative and tidal planet-star interactions in eccentric planetary systems, and constrain the atmospheric properties and mass of exoplanets solely from transmission spectroscopy.
MIT has an extraordinary, time-limited opportunity to play a central role in this historical scientific initiative to discover habitats and signs of life outside of our solar system. Our goal is to raise $1,000,000 by April to build one new SPECULOOS (1-meter) telescope by fall of 2017. We already have one potential donor at $600,000, leaving just $400,000 left to raise! Can you help? To accelerate this exoplanet research and ensure MIT can join the SPECULOOS consortium, please consider making a gift to the SPECULOOS project. Call Angela Ellis at 617-253-5796 or email firstname.lastname@example.org for information. MORE
Spitzer Hears Stellar 'Hearbeat' from Planetary Companion - NASA's Spitzer Space Telescope has detected unusual pulsations in the outer shell of a star called HAT-P-2. Scientists' best guess is that a closely orbiting planet, called HAT-P-2b, causes these vibrations each time it gets close to the star in its orbit. | NASA Press Release
ESOcast 83: Ultracool Dwarf with Planets - Astronomers using telescopes at ESO's observatories in Chile have discovered three planets around a dim dwarf star just 40 light-years from Earth. These worlds have sizes and temperatures similar to those of Venus and the Earth, and they are the best targets so far found in the hunt for life elsewhere in the Universe. | Credit: ESO
The Wild Swings of an Exoplanet - The exoplanet HD80606 b spends most of its time far from its star, but every 111 days it swings in feverishly close. NASA's Spitzer Space Telescope measured the planet's extreme temperature swings using infrared light. This allowed astronomers to simulate its atmosphere. | Visuals credit: NASA/JPL-Caltech
