The State of Astronomy Education in the U.S.
, 1996 I would like to set the scene for the discussion that will follow in this book and bring up a few disturbing points which I believe any discussion about astronomy education will ultimately have to address.

The Astrophysical Journal LettersThe correlation between the inner small planets and cold giants encodes the formation and evolution of planetary systems. It remains unclear if the correlation differs on the two sides of the radius valley.

An Eccentric Sub-Neptune Moving Into the Evaporation Desert
The Astrophysical Journal LettersThough missions such as Kepler, K2, and TESS have discovered >2000 sub-Neptune and Neptunian planets, there is a dearth of such planets at close-in ( P ≲ 3 days) orbits. This feature, called the Neptune desert or the evaporation desert, is believed to be

Biases from Missing a Small Planet in High Multiplicity Systems
The Astrophysical Journal LettersIn an era when we are charting multiple planets per system, one might wonder the extent to which “missing” (or failing to detect) a planet can skew our interpretation of the system architecture. We address this question with a simple experiment: starting

TOI-2005b: An Eccentric Warm Jupiter in Spin-orbit Alignment
The Astronomical JournalWe report the discovery and characterization of TOI-2005 b, a warm Jupiter on an eccentric ( e ∼ 0.59), 17.3 days orbit around a V _mag = 9.867 rapidly rotating F-star.
