The Tierras Observatory: Ultra-Precise Photometry for Characterizing Exoplanets and Their Host Stars

Posted by klaurent Harvard

Kavli Affiliate: David Charbonneau | Summary:The Tierras Observatory is a fully robotic 1.3-m telescope at the Fred Lawrence Whipple Observatory in southern Arizona. Tierras achieves sub-part-per-thousand (ppt) photometric precision on two timescales: intra-night, to detect and characterize transits of planets around nearby mid-to-late M dwarfs, and night-to-night across an observing season, to characterize the long-term […]

Direct imaging of vortex lattices across fractional fillings in two-dimensional Josephson junction arrays

Posted by klaurent Cornell

Kavli Affiliate: Katja C. Nowack | Summary:Josephson junction arrays are predicted to host a rich sequence of commensurate vortex lattices. However, direct imaging of these configurations remains limited, while transport measurements cannot resolve the underlying vortex arrangements or how order breaks down. Using scanning superconducting quantum interference device (SQUID) microscopy, we resolve individual vortices and […]

ALMA detection of continuum emission from GQ Lup B

Posted by klaurent Peking

Kavli Affiliate: Ruobing Dong | Summary:GQ Lup B is a massive (10-40 M$_textJup$) companion orbiting the young T-Tauri star GQ Lup A at a projected distance of $sim$110 au (0.7”). It is outside the circumprimary disk in the submm continuum, but its $sim,63^circ$ inclined orbit intersects the primary’s gas disk twice per period. We report […]
