A proposito dell\u2019inchiesta della S. Congregazione dell\u2019Indice dei libri proibiti di fine \u2018500

Il paper \u2013 diviso in tre parti \u2013 muove dai risultati della \u201cRicerca sull\u2019inchiesta della Congregazione dell\u2019Indice\u201d che ha preso in esame i codici Vaticani Latini che conservano circa 9500 liste di titoli di libri posseduti dai religiosi italiani alla fine del XVI secolo. Roberto Rusconi sviluppa una panoramica introduttiva sulle biblioteche degli ordini religiosi alla fi ne del Cinquecento. Giovanna Granata sfrutta le molteplici potenzialit\ue0 informative dell\u2019Inchiesta, sia in termini di conoscenza di tali biblioteche, sia rispetto alle modalit\ue0 di circolazione delle diverse edizioni. Rosa Marisa Borraccini prende invece in esame un caso di studio come quello del 'Confessionario' di Girolamo da Palermo per dimostrare l\u2019importanza che un testo oggi quasi del tutto sconosciuto aveva all\u2019epoca della sua produzione. This paper \u2013 divided into three sections \u2013 expands upon the work undertaken in \u201cRicerca sull\u2019inchiesta della Congregazione dell\u2019Indice\u201d, which has examined the Codici Vaticani Latini, a collection which conserves around 9.500 lists of volumes owned by Italian monks and clerics at the end of the sixteenth century. Roberto Rusconi offers an introductory overview of the libraries of religious orders at the end of the sixteenth century. Giovanna Granata analyses the findings of the Inchiesta in terms of actual library holdings and in terms of the circulation of different editions. Rosa Marisa Borraccini examines the case study of the \u201cConfessionario\u201d of Girolamo da Palermo to demonstrate the importance certain texts, although now forgotten and largely ignored, had at the time of their production and circulation

TASTE IV. Refining ephemeris and orbital parameters for HAT-P-20b and WASP-1b

We present four new light curves of transiting exoplanets WASP-1b and HAT-P-20b, observed within the TASTE (The Asiago Search for Transit timing variations of Exoplanets) project. We re-analyzed light curves from the literature in a homogeneous way, calculating a refined ephemeris and orbital-physical parameters for both objects. WASP-1b does not show any significant Transit Timing Variation signal at the 120 s-level. As for HAT-P-20b, we detected a deviation from our re-estimated linear ephemeris that could be ascribed to the presence of a perturber or, more probably, to a previously unnoticed high level of stellar activity. The rotational period of HAT-P-20 A we obtained from archival data (P_rot ~ 14.5 days), combined with its optical variability and strong emission of CaII H&K lines, is consistent with a young stellar age (< 1 Gyr) and support the hypothesis that stellar activity may be responsible of the measured deviations of the transit times.Comment: 7 pages, 4 figures, 3 tables, accepted to Astronomische Nachrichte

Variable stars in one open cluster within the Kepler/K2-Campaign-5 field: M 67 (NGC 2682)

In this paper we continue the release of high-level data products from the multiyear photometric survey collected at the 67/92 cm Schmidt Telescope in Asiago. The primary goal of the survey is to discover and to characterise variable objects and exoplanetary transits in four fields containing five nearby open clusters spanning a broad range of ages. This second paper releases a photometric catalogue, in five photometric bands, of the Solar-age, Solar-metallicity open cluster M 67 (NGC 2682). Proper motions are derived comparing the positions observed in 2013 at the Asiago's Schmidt Telescope with those extracted from [email protected] MPG/ESO images in 2000. We also analyse the variable sources within M 67. We detected 68 variables, 43 of which are new detection. Variable periods and proper-motion memberships of a large majority of sources in our catalogue are improved with respect to previous releases. The entire catalogue will be available in electronic format. Besides the general interest on an improved catalogue, this work will be particularly useful because of: (1) the imminent release of Kepler/K2 Campaign-5 data of this cluster, for which our catalogue will provide an excellent, high spatial resolution input list, and (2) characterisation of the M 67 stars which are targets of intense HARPS and HARPS-N radial-velocity surveys for planet search.Comment: 8 pages, 6 figures (2 at low resolution), 2 tables.

Acoustic Emission from a Growing Crack

Separation of crack growth signals is of fundamental importance for detecting, locating, and determining the significance of an internal flaw. The difficulty associated with modeling acoustic emission is not only in providing an accurate representation of the source mechanism, but also in determining the effect of the specimen geometry and the sensor on the acoustic emission signal

Topology-Induced Critical Current Enhancement in Josephson Networks

We investigate the properties of Josephson junction networks with inhomogeneous architecture. The networks are shaped as "quare comb" planar lattices on which Josephson junctions link superconducting islands arranged in the plane to generate the pertinent topology. Compared to the behavior of reference linear arrays, the temperature dependencies of the Josephson currents of the branches of the network exhibit relevant differences. The observed phenomena evidence new and surprising behavior of superconducting Josephson arrays as well as remarkable similarities with bosonic junction arrays.Comment: improved figures (added magnetic pattern and single junction switching) some changes in the text and in the titl
