The discovery of the optical/IR counterpart of the 12-s transient X-ray pulsar GS 0834-43
G. L. Israel,Stefano Covino,Sergio Campana,V. F. Polcaro,Paul Roche,Luigi Stella,A. Di Paola,Davide Lazzati,Sandro Mereghetti,E. Giallongo,Adriano Fontana,F. Verrecchia +11 more
TL;DR: In this article, the optical counterpart of the 12.3-s transient X-ray pulsar GS 0834−43 was discovered and two new refined positions, ∼14 and ∼18 arcsec away from the previously published one, and a new spin period measurement.
Journal ArticleDOI
X-ray emission from the luminous O-type subdwarf HD 49798 and its compact companion
Sandro Mereghetti,N. La Palombara,Andrea Tiengo,Andrea Tiengo,Andrea Tiengo,N. Sartore,Paolo Esposito,G. L. Israel,Luigi Stella +8 more
TL;DR: In this article, the authors derived an upper limit on the spin-period derivative |Pdot| <6x10^-15 s/s, more than two orders of magnitude smaller than the previously available value.
Journal ArticleDOI
A Compton reflection dominated spectrum in a peculiar accreting neutron star
Nanda Rea,Nanda Rea,Nanda Rea,Luigi Stella,G. L. Israel,Giorgio Matt,Silvia Zane,Alberto Segreto,T. Oosterbroek,Mauro Orlandini +9 more
TL;DR: In this paper, the authors report on a puzzling event that occurred during a long BeppoSAX observation of the slowly rotating binary pulsar GX 1+4. During this event, lasting about 1 d, the source X-ray flux was ove raf actor 10 lower than normal.
Journal ArticleDOI
Variability of the optical–UV continuum in NGC 5548: implications for accretion-disc models
TL;DR: The recent campaign of systematic UV and optical observations of NGC 5548 has shown the continuum to vary virtually simultaneously at ultraviolet and optical frequencies, with an upper limit to the delay of less than 4 d.
Journal ArticleDOI
Polarimetric observations of GRB 011211
Stefano Covino,Davide Lazzati,D. Malesani,Gabriele Ghisellini,G. L. Israel,Luigi Stella,Andrea Cimatti,S. di Serego,Fabrizio Fiore,Nobuyuki Kawai,Sergio Ortolani,Luca Pasquini,George R. Ricker,Paolo Saracco,Gianpiero Tagliaferri,Filippo Maria Zerbi +15 more
TL;DR: In this article, polarimetric observations performed with the VLT-UT3 (Melipal) on the afterglow of GRB 011211, 35 hours after the burst onset, yielded a 3 upper limit of P < 2:7%.
