David K. Lynch, Phd David K. Lynch, PhD Education: PhD Astronomy, University of Texas at Austin BS Astrophysics, Indiana University Dave is an astrophysicist and of late a geologist. He postdocced in the Caltech Physics Dept and the UC Berkeley Radiophysics group. Infrared spectroscopy of cosmic sources is his specialty (star formation regions, pre-main sequence stars, novae, supernovae and solar system objects). Dave has used telescopes all over the world, including NASA and USAF airborne observatories and multiple satellite telescopes. His recent work involves tectonics and geology of the Mojave and Sonora deserts. Dave has over two hundred peer-review journal publications and is currently a geophysical consultant.

    Submitted to The Astrophysical Journal Preprint typeset using LATEX style emulateapj v. 5/2/11 CONSTRAINTS ON THE PROGENITOR SYSTEM OF THE TYPE IA SUPERNOVA 2014J FROM PRE-EXPLOSION HUBBLE SPACE TELESCOPE IMAGING Patrick L. Kelly1, Ori D. Fox1, Alexei V. Filippenko1, S. Bradley Cenko2, Lisa Prato3, Gail Schaefer4, Ken J. Shen1,5, WeiKang Zheng1, Melissa L. Graham1, and Brad E. Tucker1,6 Submitted to The Astrophysical Journal ABSTRACT We constrain the properties of the progenitor system of the highly reddened Type Ia supernova (SN) 2014J in Messier 82 (M82; d ≈ 3:5 Mpc). We determine the SN location using Keck-II K-band adaptive optics images, and we find no evidence for flux from a progenitor system in pre-explosion near-ultraviolet through near-infrared Hubble Space Telescope (HST) images. Our upper limits exclude systems having a bright red giant companion, including symbiotic novae with luminosities comparable to that of RS Ophiuchi. While the flux constraints are also inconsistent with predictions for compar- atively cool He-donor systems (T . 35,000 K), we cannot preclude a system similar to V445 Puppis. The progenitor constraints are robust across a wide range of RV and AV values, but significantly greater values than those inferred from the SN light curve and spectrum would yield proportionally brighter luminosity limits. The comparatively faint flux expected from a binary progenitor system consisting of white dwarf stars would not have been detected in the pre-explosion HST imaging. In- frared HST exposures yield more stringent constraints on the luminosities of very cool (T < 3000 K) companion stars than was possible in the case of SN Ia 2011fe.

  • Appendix: Spectroscopy of Variable Stars
    Appendix: Spectroscopy of Variable Stars As amateur astronomers gain ever-increasing access to professional tools, the science of spectroscopy of variable stars is now within reach of the experienced variable star observer. In this section we shall examine the basic tools used to perform spectroscopy and how to use the data collected in ways that augment our understanding of variable stars. Naturally, this section cannot cover every aspect of this vast subject, and we will concentrate just on the basics of this field so that the observer can come to grips with it. It will be noticed by experienced observers that variable stars often alter their spectral characteristics as they vary in light output. Cepheid variable stars can change from G types to F types during their periods of oscillation, and young variables can change from A to B types or vice versa. Spec­ troscopy enables observers to monitor these changes if their instrumentation is sensitive enough. However, this is not an easy field of study. It requires patience and dedication and access to resources that most amateurs do not possess. Nevertheless, it is an emerging field, and should the reader wish to get involved with this type of observation know that there are some excellent guides to variable star spectroscopy via the BAA and the AAVSO. Some of the workshops run by Robin Leadbeater of the BAA Variable Star section and others such as Christian Buil are a very good introduction to the field. © Springer Nature Switzerland AG 2018 M.

The spectra we see from stars is the result of the complete output in visible light of the star (in simple terms).

Ellis Ave, IL 60637 Chicago Received, 17/03/2015 / Accepted, 11/05/2015 ABSTRACT Context. Circumstellar disks are considered to be the birthplace of planets. Specific structures like spiral arms, gaps, and cavities are characteristic indicators of planet-disk interaction. Investigating these structures can provide insights into the growth of protoplanets and the physical properties of the disk. Aims. We investigate the feasibility of using molecular lines to trace planet-induced structures in circumstellar disks. Methods. Based on 3D hydrodynamic simulations of planet-disk interactions obtained with the PLUTO code, we perform self- consistent temperature calculations and produce N-LTE molecular line velocity-channel maps and spectra of these disks using our new N-LTE line radiative transfer code Mol3D. Subsequently, we simulate ALMA observations using the CASA simulator. We consider two nearly face-on inclinations, five disk masses, seven disk radii, and two different typical pre-main-sequence host stars (T Tauri, Herbig Ae) at a distance of 140 pc. We calculate up to 141 individual velocity-channel maps for five molecules/isotopoloques (12C16O, 12C18O, HCO+, HCN, and CS) in a total of 32 rotational transitions to investigate the frequency dependence of the structures indicated above.

If the white dwarf is accreting hydrogen deficient material, helium shell-flash driven eruptions can occur on its surface. Thus far only one such helium nova event has been observed in Nova Puppis 2000 = V445 Pup. We have discovered an expanding bipolar shell involving fast moving ejecta of He-rich material surrounding this binary.
