THE AGB NEWSLETTER an Electronic Publication Dedicated to Asymptotic Giant Branch Stars and Related Phenomena
THE AGB NEWSLETTER An electronic publication dedicated to Asymptotic Giant Branch stars and related phenomena No. 117 | 1 February 2007 http://www.astro.keele.ac.uk/AGBnews Editors: Jacco van Loon and Albert Zijlstra Editorial Dear Colleagues, It is our pleasure to present you the 117th issue of the AGB Newsletter. Of the 21 refereed journal publications, eight deal directly with Planetary Nebulae | which may have something to do with planets after all, and perhaps with dark energy as well (see the contribution by Gibson & Schild). Don't miss the many job advertisements, both for PhD studentships (Denver, Vienna, Portsmouth) and postdoctoral fellowships (Vienna, Keele). The Food for Thought statement published last month generated some reaction. One of you considered the relation between rotation rate and magnetic activity to be the principal question in relation to AGB stars that needs to be answered. Hence, we make it this month's Food for Thought statement. Reactions to this, or suggestions for other pertinent questions, are very welcome and will be discussed in future issues of the newsletter. The next issue will be distributed on the 1st of March; the deadline for contributions is the 28th of February. Editorially Yours, Jacco van Loon and Albert Zijlstra Food for Thought This month's thought-provoking statement is: The relation between rotation rate and magnetic activity is the principal question in relation to AGB stars that needs to be answered Reactions to this statement or suggestions for next month's statement can be e-mailed to [email protected] (please state whether you wish to remain anonymous) 1 Refereed Journal Papers Magnetic ¯elds in planetary nebulae and post-AGB nebulae. -
Interstellarum 25 Schließen Wir Den Ersten Jahrgang Der Neuen Interstellarum-Hefte Ab
Liebe Leserinnen, liebe Leser, Meade gegen Celestron, das ist das große Duell der beiden Teleskopgiganten aus Amerika. Wir sind stolz darauf, als erste deutschsprachige Zeitschrift einen fairen Zweikampf der weltgröß- ten Fernrohrhersteller anbieten zu können; un- getrübt von wirtschaftlichen oder redaktionellen Vorbehalten. Dazu haben wir die neuen aufre- genden GPS-Teleskope von Meade und Celes- tron in einem Produktvergleich gegenüberge- stellt. Im ersten Teil in diesem Heft erfahren Sie mehr über Mechanik und Elektronik der beiden Computerteleskope (Seite 60); die Ergebnisse der Praxis unter den Sternen lesen Sie dann in einem kommenden Heft. Mit interstellarum 25 schließen wir den ersten Jahrgang der neuen interstellarum-Hefte ab. Ein Plus von 30% bei den Abonnentenzahlen spricht für unseren Weg, den wir konsequent fortsetzen Polarlichter in Deutschland (Foto: Thomas Jäger) werden. Dabei möchten wir verstärkt das Augen- merk auf hochqualitative Beiträge für praktisch tätige Amateurastronomen lenken. werden wir uns zusätzlich der Jupiterbeobach- tung und dem Merkurdurchgang vom 7.5.2003 2003 wird bei interstellarum zum Jahr der widmen. Schließlich stehen 2003 mit zwei Planetenbeobachtung ernannt. Auftakt ist der Mondfinsternissen und einer partiellen Sonnen- Beitrag zur Beobachtung der Saturnringe in die- finsternis drei weitere Großereignisse auf dem ser Ausgabe (Seite 34). Mit dem nächsten Heft Programm. beginnen wir zusätzlich eine intensive Vorberei- tung auf die große Mars-Opposition in diesem Was wir noch 2003 geplant haben, ist auf Sommer mit Beiträgen zu verschiedenen prakti- www.interstellarum.de nachzulesen.

Mit interstellarum 25 endet die Comic-Serie Astromax (Seite 80), die Schöpfer Rainer Töpler aus Zeitgründen aufgeben muss – vielen Dank für die sechs kurzweiligen Geschichtchen. -

Astrophysical Distance Scale II. Application of the JAGB Method: a Nearby Galaxy Sample Wendy L
Draft version May 22, 2020 Typeset using LATEX preprint style in AASTeX62 Astrophysical Distance Scale II. Application of the JAGB Method: A Nearby Galaxy Sample Wendy L. Freedman1 and Barry F. Madore1, 2 1Dept. of Astronomy & Astrophysics University of Chicago 5640 S. Ellis Ave., Chicago, IL, 60637 2The Observatories Carnegie Institution for Science 813 Santa Barbara St., Pasadena, CA 91101 ABSTRACT We apply the near-infrared J-region Asymptotic Giant Branch (JAGB) method, re- cently introduced by Madore & Freedman (2020), to measure the distances to 14 nearby galaxies out to 4 Mpc. We use the geometric detached eclipsing binary (DEB) distances to the LMC and SMC as independent zero-point calibrators. We find excellent agree- ment with previously published distances based on the Tip of the Red Giant Branch (TRGB): the JAGB distance determinations (including the LMC and SMC) agree in the mean to within ∆(JAGB T RGB) =+0.025 0.013 mag, just over 1%, where the − ± TRGB I-band zero point is MI = -4.05 mag. With further development and testing, the JAGB method has the potential to provide an independent calibration of Type Ia supernovae (SNe Ia), especially with JW ST . The JAGB stars (with M = 6:20 mag) J − can be detected farther than the fainter TRGB stars, allowing greater numbers of cal- ibrating galaxies for the determination of H0. Along with the TRGB and Cepheids, arXiv:2005.10793v1 [astro-ph.GA] 21 May 2020 JAGB stars are amenable to theoretical understanding and further refined empirical calibration. A preliminary test shows little dependence, if any, of the JAGB magnitude with metallicity of the parent galaxy. -
Born-Again Protoplanetary Disk Around Mira B M

Hayward Gemini Observatory, Casilla 603, La Serena, Chile and J. P. Lloyd Cornell University, Ithaca, NY 14853 Received 2007 February 16; accepted 2007 March 10 ABSTRACT The Mira AB system is a nearby (107 pc) example of a wind accreting binary star system. In this class of system, the wind from a mass-losing red giant star (Mira A) is accreted onto a companion (Mira B), as indicated by an accretion shock signature in spectra at ultraviolet and X-ray wavelengths. Using novel imaging techniques, we report the detection of emission at mid-infrared wavelengths between 9.7 and 18.3 m from the vicinity of Mira B but with a peak at a radial position about 10 AU closer to the primary Mira A. We interpret the mid-infrared emission as the edge of an optically-thick accretion disk heated by Mira A. The discovery of this new class of accretion disk fed by M-giant mass loss implies a potential population of young planetary systems in white dwarf binaries, which has been little explored despite being relatively common in the solar neighborhood. -

We review the research activities of nuclear astrophysics in east and southeast Asia which includes astronomy, experimental and theoretical nuclear physics, and astrophysics. Several hot topics such as the Li problems, critical nuclear reactions and properties in stars, properties of dense matter, r-process nucleosynthesis, and ν-process nucleosynthesis are chosen and discussed in further details. Some future Asian facilities, together with physics perspectives, are introduced. Keywords: Nuclear astrophysics, East and southeast Asia 1 Introduction • What are the nuclear reactions that drive the Nuclear astrophysics deals with astronomical phenomena evolution of stars and stellar explosions? involving atomic nuclei, and therefore, it is an interdis- ciplinary field that consists of astronomy, astrophysics, The research involves close collaboration among and nuclear physics. -
