STAGGER-grid of 3D stellar models. I.
We present the STAGGER-grid, a comprehensive grid of time-dependent, three-dimensional (3D), hydrodynamic model atmospheres for late-type stars with realistic treatment of... -
Mass and age of extreme low-mass white dwarfs
The number of detected extremely low mass (ELM) white dwarf stars has increased drastically in recent year thanks to the results of many surveys. In addition, some of these... -
Dust effects on photometric parameters in spirals
We present results of a study to quantify the effects of dust on the derived photometric parameters of disk and bulges obtained from bulge-disk decomposition: scale-length,... -
3 eclipsing high-mass binaries light curve
We present the first results of a comprehensive photometric O-star survey performed with a robotic twin refractor at the Universitatssternwarte Bochum located near Cerro... -
XMM-Newton Wide Angle Survey (XWAS)
We present the XMM-Newton Wide Angle Survey (XWAS), a new catalogue of almost a thousand X-ray sources spectroscopically identified through optical observations. Sources lie in... -
Eclipsing binary system LL Aquarii
The eclipsing binary LL Aqr consists of two late-type stars in an eccentric orbit with a period of 20.17d. We use an extensive light curve from the SuperWASP survey augmented by... -
Evolution and CNO yields of Z=10^-5^ stars
Our main goals are to get a deeper insight into the evolution and final fates of intermediate-mass, extremely metal-poor (EMP) stars. We also aim to investigate the C, N, and O... -
Fermi and Swift GRBs E_peak_-E_iso_ relation
We used a sample of gamma-ray bursts (GRBs) detected by Fermi and Swift to reanalyze the correlation discovered by Amati et al. (2002A&A...390...81A) between E_pi_, the peak... -
Metallicities of open clusters
Open clusters are a useful tool when investigating several topics connected with stellar evolution; for example the age or distance can be more accurately determined than for... -
Bright B-type variables in Scorpius
The first two of a total of six nano-satellites that will constitute the BRITE-Constellation space photometry mission have recently been launched successfully. In preparation... -
ALMA observations of 12CO/13CO around R Scl
The detached-shell source R Scl, displaying CO emission from recent mass loss, in a binary-induced spiral structure as well as in a clumpy shell produced during a thermal pulse,... -
X-ray spectrum of 1H0419-577
In this paper we analyze the X-ray, UV and optical data of the Seyfert 1.5 galaxy 1H0419-577, with the aim of detecting and studying an ionized-gas outflow. The source was... -
CoRoT-100866999 frequency analysis
The presence of g- and p-modes allows testing stellar models from the core to the envelope. Moreover, binarity in an eclipsing system constrains the physical parameters of the... -
FGK dwarf stars limb darkening coefficients
Limb darkening is a fundamental ingredient for interpreting observations of planetary transits, eclipsing binaries, optical/infrared interferometry and microlensing events.... -
Blazar 0836+710 long-term multiwavelength studies
The observation of gamma-ray flares from blazar 0836+710 in 2011, following a period of quiescence, offered an opportunity to study correlated activity at different wavelengths... -
LDN 1570 BV(RI)c polarisation and photometry
We wish to map the magnetic field geometry and to study the dust properties of the starless cloud, L1570, using multiwavelength optical polarimetry and photometry of the stars... -
BVRI observations of the FUor star V582 Aur
We present results from optical photometric and spectroscopic observations of the eruptive pre-main sequence star V582 Aur. Variability of the star was reported a few years ago... -
Transitions in OMC-2 FIR 4 in the far-IR
Broadband spectral surveys of protostars offer a rich view of the physical, chemical and dynamical structure and evolution of star-forming regions. The Herschel Space... -
Multi-color photometry of star-forming galaxies
We estimate the galaxy stellar mass function and stellar mass density for star-forming and quiescent galaxies with 0.2 -
Period-mass-loss rate relation of Miras
We report the discovery that Mira variables with and without absorption lines of the element technetium (Tc) occupy two different regions in a diagram of near- to mid-IR colour...
