Vol. 46, No. 2 The OBSERVER of the Twin City Amateur Astronomers February 2021 PRESIDENT’S NOTE The OBSERVER I dedicate this month's President's Note space is the monthly electronic newsletter of to Carl Wenning. He will soon be stepping down as Twin City Amateur Astronomers, Inc., a registered 501(c)(3) non-profit editor of The OBSERVER after a term of seven years educational organiz-ation of amateur that predates my re-entry into TCAA and culminates astronomers interested in studying with the March 2021 issue. His success as editor of astronomy and sharing their hobby our newsletter is indisputable. In addition to with the public. elevating its format, overseeing its transition from a physical newsletter to an emailed PDF, and TCAA OFFICERS & CHAIRPERSONS contributing countless quality features and articles, President, Director, & Property Manager he received the Astronomical League 2017 Mable Tim Stone 309-531-2401 Sterns Newsletter Award. He would tirelessly gather [email protected] tidbits from around the club and assemble the “AstroBits” feature every month – a feature I have Vice President & Director/Membership TCAA President Tim Stone Coord. very much enjoyed. His articles on various aspects of Tom Willmitch 309-846-2423 astronomical observation and theory were always informative. I sincerely hope that Carl, [email protected] like me, will continue to be a regular contributor to our newsletter. Treasurer & Director/Registered Agent We have all benefited greatly from the time and talent he generously gave to editing Dave Osenga 309-287-0789 our newsletter. He genuinely enjoys writing and derived a great deal of joy from its [email protected] production, even though, at times, it must have felt like a thankless job. I am personally Assistant Property Manager/ALCor grateful for his acceptance of articles I would submit, even if their quality was sometimes Scott Wade 309-310-2464 [email protected] a matter of question. As a professional writer, I'm sure he swallowed hard more than a few times as he read some of my rambling sentences and tense disagreements. I learned th 5 Director a lot from Carl simply by reading how he wrote, as much as by reading what he wrote.

I hope ya’ll’ve remembered your favorite coping mechanism for dealing with the long hot summers we have down here in the bayou state, or, at the very least, are making peace with the short nights that keep us from enjoying both a good night’s sleep and a productive observing/imaging session (as if we ever could get a long enough break from the rain for that to happen anyway). At any rate, we figured now would be as good a time as any to get the gang back together for a good old fashioned potluck style barbecue: to that end, we’ve moved the July meeting to the Sunday, 11 July at 4PM at HRPO.

Ina Road, Suite D Tucson, Arizona 85704 William K. Hartmann Manager TASK 1: ASTEROID SPECTROPHOTOMETRY AND INTERPRETATION (Principal Investigator: Clark R. Chapman) A.* INTRODUCTION The asteroid research program during 1974/5 has three major goals: (1) continued spectrophotometric reconnaissance of the asteroid belt to define compositional types; (2) detailed spectrophotometric observations of particular asteroids, especially to determine variations with rotational phase, if any; and (3) synthesis of these data with other physical studies of asteroids and interpretation of the implications of physical studies of the asteroids for meteoritics and solar system history. The program has been an especially fruitful one, yielding fundamental new insights to the nature of the asteroids and the implications for the early development of the terrestrial planets. In particular, it is believed that the level of understanding of the asteroids has been reached, and sufficiently fundamental questions raised about their nature, that serious consideration should be given to possible future spacecraft missions directed to study a sample of asteroids at close range. Anders (1971) has argued that serious consideration of asteroid missions should be postponed until ground-based techniques for studying asteroids had been sufficiently exploited so that we could intelligently select appropriate asteroids for spacecraft targeting. It is clear that that point has been reached, ,and now that relatively inexpensive fly-by missions have been discovered to be possible by utilizing Venus and Earth gravity assists (Bender and Friedlander, 1975), serious planning for such missions ought to begin.

We already knew Mercury was bizarre. A planet of extremes, during its day facing the sun, its surface temperature tops 800°F —hot enough to melt lead—but during the night, the temperature plunges to -270°F, way colder than dry ice. Frozen water may exist at its poles. And its day (from sunrise to sunrise) is twice as long as its year. Now add more weirdness measured by NASA’s recent MESSENGER spacecraft: Mercury’s magnetic field in its northern hemisphere is triple its strength in the southern hemisphere. Numerical models run by postdoctoral researcher Hao Cao, working in the lab of Christopher T. Russell at UC Los Angeles, offer an explanation: inside Mercury’s molten iron core it is “snowing,” and the resultant convection is so powerful it causes the planet’s magnetic dynamo to break symmetry and concentrate in one hemisphere. “Snowing” inside Mercury With a diameter only 40 percent greater than the Moon’s, Mercury is the smallest planet in the solar system (now that Pluto was demoted). But its gravitational field is more than double the Moon’s.

  • Variable Stars Across the Observational HR Diagram
    Variable stars across the observational HR diagram Laurent Eyer1, Nami Mowlavi1;2 1 Observatoire de Gen`eve, Universit´ede Gen`eve, 1290 Sauverny, Switzerland 2 ISDC, Universit´ede Gen`eve, 1290 Versoix, Switzerland E-mail: [email protected] Abstract. An overview of pulsating variable stars across the observational Hertzprung-Russel (HR) diagram is presented, together with a summary of their global properties. The HR diagram is presented with a third colour-coded dimension, visualizing the fraction of variable, the amplitude of variability or the period of variability. The distribution of variable stars in the other observational diagrams, such as the Period-Amplitude diagram, is also presented. Some of the progresses performed in the field of variable stars during the last decade are briefly summarized, and future projects that will improve our knowledge of variable stars are mentioned. 1. Introduction There are in the literature several global descriptions of variable stars. We can mention four books, one by Richter, Wenzel and Hoffmeister (1985, out of print), one by Sterken and Jaschek [1], one by Percy ([2]) and one, soon to come, by Aerts et al. [3]. There have also been two excellent and detailed reviews by Gautschy and Saio ([4], [5]) about a decade ago. With the advent of Charge-Coupled Devices (CCDs) and large scale surveys like the Optical Gravitational Lensing Experiment (OGLE), the Massive Compact Halo Object project (MACHO) or the "Exp´eriencepour la Recherche d'Objets Sombres" (EROS), the subject of variable star studies is now under a remarkable expansion. As we will see the expansion will continue in the coming decade because there are many future projects which will sample frequently large regions of the sky.
