Publikováno v: Monthly Notices of the Royal Astronomical Society. 505:6121-6154

We have identified a first group of 33 new candidates for symbiotic stars (SySt) of the accreting-only variety among the 600,255 stars so far observed by the GALAH high-resolution spectroscopic survey of the Southern Hemisphere, more than doubling th

Persistent nuclear burning in Nova Sgr 2016 N.4 (= V5856 Sgr = ASASSN-16ma) six years past its outburst

Autor: U. Munari, N. Masetti, F. M. Walter, R. E. Williams, F.-J. Hambsch, A. Frigo, P. Valisa

We report on the fast Nova Sgr 2016 N.4 being surprisingly trapped in a long-lasting and bright plateau (Delta I >= 10 mag above quiescence) six years past the nova eruption. Very few other novae experience a similar occurrence. We carried out an int

Revisiting the post-common-envelope binaries HZ 9, KV Vel and Abell 65

Autor: J. Rey, R. Hinojosa, E. C. Puebla, Nikolaus Vogt, A. Contreras-Quijada, J. Aranda, V. Gotta, F. J. Hambsch, C. Rios-Venegas, R. Jerez, J. I. Villaseñor

Publikováno v: Monthly Notices of the Royal Astronomical Society. 493:1197-1203

New time-resolved photometric observations of three close but detached white dwarf/red dwarf binaries have enabled an in-depth analysis of their properties, combining new data with known information. For HZ 9, time-resolved photometric data have not

Dynamical masses for two M1 + mid-M dwarf binaries monitored during the SPHERE-SHINE survey

Publikováno v: Astronomy and Astrophysics-A&A
Astronomy and Astrophysics-A&A, 2022, 658, ⟨10.1051/0004-6361/202142438⟩

We present orbital fits and dynamical masses for HIP 113201AB and HIP 36985AB, two M1 + mid-M dwarf binary systems monitored as part of the SPHERE SHINE survey. To robustly determine ages via gyrochronology, we undertook a photometric monitoring camp

Digital signal processing application in nuclear spectroscopy

Autor: O. V. Zeynalova, Sh. S. Zeynalov, F.-J. Hambsch, S. Oberstedt

Publikováno v: Âderna Fìzika ta Energetika, Vol 10, Iss 2, Pp 214-219 (2009)

Digital signal processing algorithms for nuclear particle spectroscopy are described along with a digital pile-up elimination method applicable to equidistantly sampled detector signals pre-processed by a charge-sensitive preamplifier. The signal pr
