The Sun is not a rigid body and it is well known that its surface rotation is differential, the polar regions rotating substantially slower than the equator...

T CrB is a symbiotic recurrent nova that last erupted in 1946. Given its recurrence time-scale of approximately 80 yr, the next outburst is eagerly anticipated...

The first X-ray observation of the Seyfert 2 galaxy NGC 5252 is reported. ASCA Astro-D collected approximately 4000 photons per detector, enough to perform an...

HD 209458b was the first transiting planet discovered, and the first for which an atmosphere, in particular Na I, was detected. With time, it has become one of...

Thanks to Integral Field Unit survey data, it is possible to explore in detail the link between the formation of the stellar content in galaxies and the drivers...

We present the image and catalogue of the 14.3 μ shallow survey of 0.55 square degrees in the region of the Lockman Hole (10^h52^m03^s +57°21'46'', J2000) with...

ISOPHOT covers the largest wavelength range on ISO from 2.5 to 240μm. Its scientific capabilities include multi-filter and multi-aperture photometry...

All observations by the aperture photometer (PHT-P) and the far-infrared (FIR) camera section (PHT-C) of ISOPHOT included reference measurements against stable...

Chemical evolution models predict a gradual build-up of 13C in the Universe, based on empirical nuclear reaction rates and assumptions on the properties of...
