LVAAS General Meeting
Sunday April 2, 7 p.m. at LVAAS South Mountain Grady Planetarium
and on Zoom.
Chromospheric Activity in Sun-like Stars
and the Mystery of the Maunder Minimum
The Sun's magnetic activity consistently fluctuates on an 11-year cycle.
The only exception to this was the Maunder Minimum in the 1700’s, when the Sun’s cycle flatlined,
and almost no sunspots were observed for 80 years.
Activity cycles in other stars like the Sun have been observed for years,
leading to the recent discovery of another star like our Sun,
entering a mysterious Magnetic Maunder Minimum.
Anna Baum is a 3rd year Physics PhD student at Lehigh University.
She graduated from Penn State University in 2020 with a Bachelor of Science in Astronomy & Astrophysics.
In 2022, she published a paper on the chromospheric activity in Sun-like stars
and the discovery of a star entering a Maunder Minimum.
She is currently conducting research on eclipsing binary stars and asteroseismology,
and is always excited to learn more about stars.
