2023 General Meetings Special Events

CAS Monthly Meetings and Astronomical Programs are held the Saturday closest to the Full Moon at the Mars Hill Campus of Lowell Observatory, Hendricks Center for Planetary Studies Auditorium (6:45 pm - 8:00 pm., unless otherwise noted) followed by refreshments, and informal discussion. Meetings are open free to the public.


Saturday, January 7, 2023
Presenter Jeronimo Vasquez and Bryan Bates

Title: “The Mayan Calendar: Its cultural roots and Astro-mathematical foundations”

Through long-term observation of the sky, the Maya documented the movement of the planets and stars and built the most fascinating and accurate calendars known.

It was predicted that the world would end (yet again) on Dec 21, 2012 when the Maya Calendar reached its first Baktun Anniversary since the Mayan leader-deity Maize God raised up the sky with the sacred Ceiba Tree. The world never ended because the Maya never predicted the ending, but rather based their calendar on cycles that repeat over time.

All are welcome.

Presenter Dr. Padraig Houlahan

Title: “Your first telescope - Getting started in Astronomy”

Got a telescope over the holidays, or plan to get one? Padraig will be discussing how to choose a telescope and what you might reasonably expect to observe. He will review the different types of telescopes available to the amateur astronomer, their basic optics, and show how you can easily take lunar photographs using your cellphone camera with a telescope.

If you have questions about your new telescope, bring it and Padraig and other CAS members will be happy to answer them.

Background: Dr. Houlahan received his BA in Theoretical Physics from Trinity College Dublin, Ireland, and his MA and PhD in Astronomy from the University of Texas, Austin. Padraig was Director of Information Technology at Lowell Observatory, and in 1995 Asteroid Houlahan (8407) was named in his honor. He has taught at both Coconino Community College and Embry-Riddle Aeronautical University in Astronomy and Physics.

Presenter Dr. Tyler Richey-Yowell, Lowell Observatory

Title: “The Evolution of (what we know about the potential habitability of planets around) K Stars ”

Efforts to discover and characterize habitable zone planets have primarily focused on Sun-like stars and M dwarfs. Yet the intermediate K stars provide an appealing compromise between these two extremes that has been relatively unexplored. Compared to solar-type stars, K stars are more abundant, maintain longer main-sequence lifetimes, and their planets are more suitable to observations based on the mass and radius ratios of the planet to star. While M stars also excel in these regards, they have been observed to have frequent flares with ultraviolet (UV) energies over 100 times greater than anything observed in the recent history of our Sun.

Background: Dr. Tyler Richey-Yowell is Lowell Observatory’s first Percival Lowell Postdoctoral Fellow. She is interested in habitability and the star-planet connection. During her academic career, she has been able to work with data from optical telescopes ranging in size from 4.2 cm to 10 meters, and radio dishes even larger (VLA). She hopes to work with gamma rays at some point in the future.

Directions for Williams

Location:Glassburn Park - in the natural area west of Rod’s Steakhouse parking lot.
