MATTIA LIBRALATO is an academic who published a paper in 2016 entitled WISEP J060738.65+242953.4: A Nearby. Pole-On L8 Brown Dwarf with Radio Emission. MATTIA LIBRALATO published this work as part of a team: Gizis, John E.. Here is a description of this work: We ,,resent a simultaneous, multi-wavelength campaign targeting the nearby (7. 2 pc) L8/L9 (optical/near-infrared) dwarf WISEP J060738. 65242953. 4 in the mid-infrared, radio, and optical. Spitzer Space Telescope observations show no variability at the 0. 2% level over 10 hours each in the 3. 6 and 4. 5 micron bands. Kepler K2 monitoring over 36 days in Campaign 0 rules out stable periodic signals in the optical with amplitudes great than 1. 5% and periods between 1. 5 hours and 2 days. Non-simultaneous Gemini optical spectroscopy detects lithium, constraining this L dwarf to be less than ∼ 2 Gyr old, but no Balmer emission is observed. The low measured projected rotation velocity (v sin I <, 6 km sâˆ'1) and lack of variability are very unusual compared to other brown dwarfs, and we argue that this substellar object is likely viewed pole-on. We detect quiescent (non-burst.
