Henrietta Swan Leavitt (1868-1921) could measure the brightness of a star to a precision of about 1%.

Now, we make precise brightness measurements to study exoplanets transiting their stars.

The NASA Transiting Exoplanet Survey Satellite (TESS) is searching millions of stars for transiting planets.

Are you interested in… • observing TESS candidate planets
with ground-based telescopes • working for independent study credit
…?
Are you willing to learn… • how to observe transiting planets with
the SBO telescopes • how to work collaboratively in a world-
wide community of observers
…?
Are you… • creative • curious • kind
…?

I am looking for roughly 4-6 students to join a team to observe exoplanets from SBO.
To apply, email zach.bertathompson:
• a brief resume/CV • your general evening availability
during spring 2020 • a cool astronomy plot you made and a
brief description of something interesting you see in it
