The Total Eclipse en la Frontera program provided informal and formal science education outreach using Sul Ross State University’s La Frontera Research Initiative (LFRI) mobile program, which serves communities located along the southwest Texas-Mexico border. With assistance from existing community partnerships, the Jay M. Pasachoff Solar Eclipse Mini-Grants Program, and the National Science Foundation Noyce program, our program reached over 20,000 people within a 6-month period. LFRI provided educational experiences to Uvalde CISD (4,041 students), Eagle Pass ISD (14,028 students), San Felipe Del Rio CISD (9,874 students), Southwest Texas Junior College (2,300 students), Sul Ross State University (2,071 students), and surrounding private schools, public libraries, and the general public. Established partnerships included the above institutions, as well as Presidio ISD, Marfa ISD, Alpine ISD, the Science Mill Museum, McDonald’s Observatory, NASA's Marshall Space Flight Center, and the National Solar Observatory. Leveraging a mobile STEM Lab, LFRI provided eclipse-themed makerspace programing along with eclipse-focused educator training to include cultural total eclipse lectures with national experts to the communities along the southwest Texas-Mexico border. Specifically, border communities of Eagle Pass, Del Rio, Uvalde, and the Big Bend Region experienced STEM education outreach throughout the summer of 2023 leading up to the Total Eclipse in April 2024. Program outcomes provide a glimpse on the use of mobile makerspace program might increase STEM identity, self-efficacy, and engagement of isolated communities through a 2-year mentoring program connecting faculty, graduate students, preservice teachers, K12 educators, and community college students.

Abstract We show that a small but measurable shift in the eclipse midpoint time of eclipsing binary (EBs) stars of ∼0.1 s over a decade baseline can be used to directly measure the Galactic acceleration of stars in the Milky Way at ∼kiloparsec distances from the Sun. We consider contributions to the period drift rate from dynamical mechanisms other than the Galaxy’s gravitational field and show that the Galactic acceleration can be reliably measured using a sample of Kepler EBs with orbital and stellar parameters from the literature. The contribution from tidal decay we estimate here is an upper limit assuming the stars are not tidally synchronized. We find there are about 200 detached EBs that have estimated timing precision better than 0.5 s, and for which other dynamical effects are subdominant to the Galactic signal. We illustrate the method with a prototypical, precisely timed EB using an archival Kepler light curve and a modern synthetic HST light curve (which provides a decade baseline). This novel method establishes a realistic possibility to constrain dark matter substructure and the Galactic potential using eclipse timing to measure Galactic accelerations, along with other emerging new methods, including pulsar timing and extreme-precision radial velocity observations. This acceleration signal grows quadratically with time. Therefore, given baselines established in the near future for distant EBs, we can expect to measure the period drift in the future with space missions like JWST and the Roman Space Telescope.more » « less
