INES Access Guide No. 3 Classical Novae INES Access Guide No. 3 Classical Novae Compiled by: Angelo Cassatella Consiglio Nazionale delle Ricerche IFSI (Roma) and Rosario Gonz´alez-Riestra XMM Science Operations Centre ESAC (Madrid) and Pierluigi Selvelli Consiglio Nazionale delle Ricerche IASF (Roma), INAF-OAT (Trieste) Scientific Coordinator for the INES Acess Guides Dr. Willem Wamsteker 1 2 FOREWORD The INES Access Guides The International Ultraviolet Explorer (IUE) Satellite (launched on 26 January 1978 and in or- bit until September 1996) Project was a collaboration between NASA, ESA and the PPARC. The IUE Spacecraft and instruments were operated in a Guest Observer mode to allow Ultraviolet Spec- trophotometry at two resolutions in the wavelength range from 115nm to 320nm: low resolution ∆λ/λ=300 (≈1000 km sec−1) and a high resolution mode ∆λ/λ=10000 (≈19 km sec−1). The IUE S/C, its scientific instruments as well as the data acquisition and reduction procedures, have been described in “Exploring the Universe with the IUE Satellite”, Part I, Part VI and Part VII (ASSL, volume 129, Eds. Y. Kondo, W. Wamsteker, M. Grewing, Kluwer Acad. Publ. Co.). A complete overview of the IUE Project is given in the conference proceedings of the last IUE Conference “Ultra- violet Astrophysics beyond the IUE Final Archive” (ESA SP-413, 1998, Eds. W. Wamsteker and R. Gonz´alezRiestra) and in “IUE Spacecraft Operations Final Report” (ESA SP-1215, 1997, A. P´erez Calpena and J. Pepoy). Additional information on the IUE Project and its data Archive INES can be found at URL http://sdc.laeff.esa.es. From the very beginning of the project, it was expected that the archival value of the data obtained with IUE would be very high. This expectation has been borne out fully. Even today, IUE data are still retrieved from the Archives at a rate of ≈ 5 spectra/hour, 24 hrs/day 365 day/yr. During the operational phase of the IUE Project, the ULDA/USSP (Uniform Low Dispersion Archive/ULDA Support Software Package) was developed by ESA (Wamsteker et al., 1989, Astron. Astrophys. Suppl. Ser., Vol. 79, pg. 1-10) in preparation for the final archival disposition. The extremely good reception of this distributed Archive model by the scientific community, has led to the decision to develop the Final Archive server with a similar philosophy in the form of INES (IUE Newly Extracted Spectra). The INES system is again a complete data system, removing for nearly all the data usage the need of specialist knowledge of instrumental peculiarities. The various aspect of the INES System are described in: • W. Wamsteker, I. Skillen, J.D. Ponz, A. de la Fuente, M. Barylak, I. Yurrita, 2000, INES: Astronomy Data Distribution for the Future, Ap&SS, 273, p.155-161. • P.M. Rodr´ıguez-Pascual, R. Gonz´alez-Riestra, N. Schartel, W.

These five publications contain essentially all information needed for the use of IUE data from the INES system. The INES system represents an early prototype of what is presently being pursued 3 by the various Astronomical Virtual Observatory (AVO) initiatives. Currently, 19 National Hosts maintain functional installations of the INES system, giving access to all 104000 IUE Spectra directly for the end user, with a Principal Center (INTA/LAEFF) at URL http://sdc.laeff.esa.es. All INES (and ULDA) Guides are on-line accessible through the principal center at this URL, but access is also possible through the National Hosts. The quantity of data in the IUE Archive is sufficiently large that it is not necessarily simple to address the data efficiently in the context of an astrophysical problem, even though access to the data is extremely easy. Therefore the series of INES Access guides is intended to facilitate the use of the IUE Archive for scientists with a specific astrophysical problem in mind. The series of INES Access Guides follows the model of the ULDA Guides. Most of the information collected in the ULDA Guides 1-8 continues to be valid, but as they were mostly completed before the end of orbital operations for the IUE Project, they are not guaranteed to be complete for all data in the INES system. These Guides consist of a number of subject-oriented books, for which a specialist in the field has been invited to take the scientific responsibility. INES Access Guide No.3 treats the data of all Novae observed with IUE and has been compiled by Dr. A. Cassatella of IFSI-CNR, Rome, Italy, Dr. R. Gonz´alezRiestra of the XMM-Newton Operations Centre, ESAC, Madrid, Spain and Dr. P. Selvelli of IASF-CNR, Rome, and INAF-OAT, Trieste, Italy. The list of previously published INES/ULDA Access Guides is given below. For details of the access to INES through the National Hosts we refer to the details supplied at the above-mentioned URL, or recommend you to contact the INES Helpdesk at the LAEFF at VILSPA, Madrid, Spain ([email protected]).

II. LRS SPECTRA The sample consists of 304 carbon stars with entries in the LRS catalog (Papers I-III). The LRS spectra have been divided into three groups. Group I consists of nine stars with 9.7 and 18 tun silicate features in their LRS spectra pointing to oxygen-rich dust in the circumstellar shell. These sources are discussed in Paper I. The remaining stars all have spectra with carbon-rich dust features. Using NIR photometry we have shown that in the group II spectra the stellar photosphere is the dominant continuum. The NIR color temperature is of the order of 25OO K. Paper II contains a discussion of sources with this class of spectra. The continuum in the group III spectra is probably due to amorphous carbon dust.

  • The Orbital Ephemeris of the Classical Nova RR Pictoris: Presence of A
    Draft version August 5, 2018 Preprint typeset using LATEX style AASTeX6 v. 1.0 THE ORBITAL EPHEMERIS OF THE CLASSICAL NOVA RR PICTORIS: PRESENCE OF A THIRD BODY? N. Vogt1, M. R. Schreiber1, F.-J. Hambsch3,4, G. Retamales1, C. Tappert1, L. Schmidtobreick2 & I. Fuentes-Morales1 1Instituto de F´ısica y Astronom´ıa, Universidad de Valpara´ıso, Valpara´ıso, Chile 2European Southern Observatory, Santiago 19, Chile, Casilla 1900 3Vereniging Voor Sterrenkunde (VVS), Oude Bleken 12, 2400 Mol, Belgium 4 American Association of Variable Star Observers, 49 Bay State Rd., Cambridge, MA02138, USA ABSTRACT The ex-nova RR Pic presents a periodic hump in its light curve which is considered to refer to its orbital period. Analyzing all available epochs of these hump maxima in the literature, and combining them with those from new light curves obtained in 2013 and 2014, we establish an unique cycle count scheme valid during the past 50 years, and derive an ephemeris with the orbital period 0.145025959(15) days. The O - C diagram of this linear ephemeris reveals systematic deviations which could have different causes. One of them could be a light-travel-time effect caused by the presence of a hypothetical third body near the star/brown dwarf mass limit, with an orbital period of the order of 70 years. We also examine the difficulty of the problematic of detecting sub-stellar or planetary companions of close red- dwarf white-dwarf binaries (including cataclysmic variables), and discuss other possible mechanisms responsible for the observed deviations in O - C. For RR Pic, we propose strategies in order to solve this question by new observations.

Gammastrahlen mit 1,8 MeV, und das 26Mg-Isotop. • Das Besondere an dem Molekül ist, dass es das erste eindeutig nachgewiesene radioaktive Molekül im Weltraum ist. Wo wurde dieses Molekül entdeckt? • Es wurde in einem Low-mass-Binary-System nachgewiesen, bei dem zwei Sterne miteinander verschmolzen sind, wobei eine dieser Komponenten ein roter Riese in einem späten Entwicklungsstadium mit einer Masse von ca. 0,8- 2,5 Sonnenmassen war. Die Quelle heißt CK Vulpeculae (CK Vul). • Das Objekt fiel erstmals 1670 auf, als man einen Helligkeitsausbruch bei dem Stern wahrnahm. Zunächst ging man davon aus, dass dieser Ausbruch eine Nova wäre, doch seit 2015 ist bekannt, dass der Ausbruch durch die Kollision und Verschmelzung zweier Sterne zustande kam. • Kürzlich wurde entdeckt, dass CK Vul auch mit einer erheblichen Menge an Staub und molekularem Gas in Verbindung gebracht werden kann.

CP Pup (Nova Pup 1942) showed outburst and quiescent characteristics indicating a very massive white dwarf, yet the standard spectroscopic dynamical analysis assuming an accretion disk yields an extremely low value for the white dwarf mass. However, some physical parameters and the accretion geometry are still poorly known. Aims. The nova was spectroscopically monitored between 1988 and 1996. We analyzed the whole data set in order to re-determine the spectroscopic period and examine its stability. We also looked for chemical anomalies in the spectrum. Methods. We obtained the radial velocity curves for the hydrogen and helium lines from our last better quality 1996 run. The mean 1996 spectrum yields information on the chemical composition of the binary. We also searched the mean period using the multi-year data set. Results. From the radial velocities of our complete data set we derive the most probable mean spectroscopic period and tentatively suggest revised ephemeris.

What more can I say. If you have not made plans for a road trip, you can help out at HRPO. All who are going on a road trip be prepared to share pictures and experiences at the September meeting. BRAS has lost another member, Bart Bennett, who joined BRAS after Chris Desselles gave a talk on Astrophotography to the Cajun Clickers Computer Club (CCCC) in January of 2016, Bart became the President of CCCC at the same time I became president of BRAS. The Clickers are shocked at his sudden death via heart attack. Both organizations will miss Bart. His obituary is posted online here: http://www.rabenhorst.com/obituary/sidney-barton-bart-bennett/ Last month’s meeting, at LIGO, was a success, even though there was not much solar viewing for the public due to clouds and rain for most of the afternoon. BRAS had a table inside the museum building, where Ben and Craig used material from the Night Sky Network for the public outreach.
