National Capital Astronomers

Membership Application rates reduced

Serving science and society since 1937. The National Capital Astronomers (NCA) is a non-profit, membership supported, volunteer run, public service corporation dedicated to advancing space technology, astronomy, and related sciences through information, participation, and inspiration, via research, lectures and presentations, publications, expeditions, tours, public interpretation, and education. NCA is the astronomy affiliate of the Washington Academy of Sciences. We are also members of the Astronomical League, in fact NCA members helped form the Astronomical League a long time ago.

NCA has for many years published a monthly newsletter called Star Dust that is available for members. Besides announcement of coming NCA meetings and a calendar of monthly events Star Dust contains reviews of past meeting and articles on current astronomical events.

NCA is a very unusual astronomy organization. All are welcome to join. "Everyone who looks up to the sky with wonder is an astronomer" and welcomed by NCA. You do not have to own a telescope, but if you do own one that is fine, too. You do not have to be deeply knowledgeable in astronomy , but if you are knowledgeable in astronomy that is fine, too. You do not have to have a degree, but if you do that is fine, too. WE ARE THE MOST DIVERSE local ASTRONOMY CLUB anywhere. Come to our meetings and you will find this out. WE REALLY MEAN THIS!

Monthly Meetings with Educational Presentations are Open to the Public with No Admission Charge

Next Meeting Date is Saturday, June 14, 2008

7:30 pm at the University of Maryland Observatory on Metzerott Road.

Speaker Dr. Harold Alden Williams

on the topic

Stellar E V O LU T I O N from 0. 0 8 to 1 0 0 Solar Masses:
What Everybody Should Know;
& Q U A S I S T A R S

On Saturday, June 14, 2008

Biographical Background

Dr. Harold Williams is a long time member of NCA: from August 1994 through 1996 he was vice president and program chair, and then president from 1996 through 1998 and again in 2005 through August 2007. He is currently NCA’s webmaster and has been doing this since November 1996, when NCA went on the net. He gets paid money for working at the Takoma Park/Silver Spring campus of Montgomery College as planetarium coordinator and physics and geology lab coordinator (full time staff position) and adjunct professor, who usually teaches astronomy in the planetarium, but has also taught physics, mathematics, geology, and physical oceanography. He is a labor union member of AFSCME (American Federation of State County and Municipal Employees) local 2380, Montgomery College Staff Union. He has previously been on the executive board, vice president, president, vice president, and now back on the executive board of this labor union. As the adjunct professors at Montgomery College are now forming a labor union he has joined SEIU (Service Employee International Union) local 500. He is a union steward and union organizer participating in several successful organizational campaigns for public employees. He grew up in Jacksonville, Florida; and is educated beyond his intelligence with a B.S. in physics and mathematics from Florida State University in Tallahassee, an M.S. in physics from the State University of New York at Stony Brook, (where he imprudently tried to solve the problem of quantum gravity, before it was generally appreciated how hard of a problem this is), and finally a Ph.D. in astrophysics from Louisiana State University in Baton Rouge with a dissertation on “Star Formation, Using 3-D Explicit Eulerian Hydrodynamics.” So he used to be a computing scientist and still has some ambitions to compute again, this time using distributive computing for high performance computing at Montgomery College. He provides a place to meet for a group of NCA members and some Montgomery College students who are studying “Geometrical Algebra/Clifford Algebra.” He has a very good opinion of himself.

Abstract

Following the advice of Wayne Warren he has decided to speak to NCA on Stellar evolution from 0.08 to 100 solar masses: what everybody should know. But the title of the talk is slightly longer, since he is currently trying to understand Quasistars are a proposed new type of astrophysical object, currently of which we have no direct astronomical observations. However, they would explain the formation of Active Galactic Nuclei and the large black holes in the center of many galaxies and how they could form so early in the history of the universe. So the longer title of the June talk is Stellar evolution from 0.08 to 100 solar masses: what everybody should know; and Quasistars. The physics of stellar structure and evolution is similar for stars and quasistars. PowerPoint presentation used during the lecture is here as promised during the lecture.

Followed by an Observing Session for NCA members and guests after the meeting
around 9pm if clear at the observatory

About Our Meetings

NCA has regular monthly meetings September through June on the second Saturday of the month.
historically NCA does not have a monthly meeting in July or August, but who knows we might change this and meet in July and August.

Some Past Meetings, by no means even most.

Public transportation: when we meet at the University of Maryland Observatory on Metzerott Road contact Elizabeth if you need a ride from the Metro to dinner or to the Observatory.
Inclement weather: In case of severe weather (tornado/snow/impassable roads), a notice will be placed on the
UMCP Website on the day of the meeting. (Be sure to shift-ctrl-reload to force your browser to reload.)

Telescope-Making and Mirror-Grinding Class

New: Telescope-making and mirror-making classes with Guy Brandenburg at the Chevy Chase Community Center, at the intersection of McKinley Street and Connecticut Avenue, NW, a few blocks inside the DC boundary, on the northeast corner of the intersection, in the basement (wood shop), on Fridays, from 6:30 to 9:30 PM.

Come See the Stars at Exploring the Sky!

Exploring the Sky is an informal program that for nearly fifty years has offered monthly opportunities for anyone in the Washington area to see the stars and planets through telescopes from a location within the District of Columbia. Sessions are held in Rock Creek Park once each month from April through November on a Saturday night starting shortly after sunset. Meet in the field just south of the intersection of Military and Glover Roads, NW near the Nature Center.
