The SAG15 report has been compiled between December 2015 and June 2017, based on community input from the EXOPAG, exoplanet, and NExSS communities. This page is an archive of the draft reports and relevant presentations. The final SAG15 report can be found on the SAG15 page.

About SAG15:

The SAG15 study is led by Daniel Apai (University of Arizona). The SAG15 team is charged with studying high-level science questions that can be answered by direct imaging studies of exoplanets and identifying the type and quality of data these studies require. The SAG15 study does not focus on any particular telescope architecture or observational method, but on the fundamental science questions.

Meteorites: Time Capsules of the Solar System

Just before 4 a.m. on June 2, Arizona’s night sky seemed to momentarily catch fire. A meteor, about 5-feet across, burned through the atmosphere at 40,200 mph, according to NASA estimates. The small debris that reached the Earth’s surface are called meteorites, and...

The curious case of KIC 8462852

The curious case of KIC 8462852 by Theodora Karalidi   Discovering the first planet, other than our Earth, that hosts life is one of the holy grails of astronomy. This is a difficult task since planets that could host life are pretty small compared to their...

Exoplanets around Red Dwarf Stars

Exoplanets around Red Dwarf Stars by Gijs Mulders   Since the discovery in 1995 of the first exoplanet over two-thousand exoplanets have been discovered. Most exoplanets, such as those discovered by the Kepler spacecraft, orbit stars similar in mass to the sun....

First Results From the Scorpion Planet Survey

By Kevin Wagner Searching for planets outside of our own solar system is one of the great challenges in modern astronomy. The problem consists of measuring the brightness of a planet that is more than a million times fainter than its host star, while being so close to...
