New insights on the complex planetary nebula Hen 2 - 113 ⋆
We report infrared observations of the planetary nebula Hen 2-113 obtained with VLT/NACO, VLTI/MIDI, VLT/ISAAC and TIMMI at the ESO 3.6m. Hen 2-113 exhibits a clear ring-like structure superimposed to a more diffuse environment visible in the L' (3.8µm), M' (4.78µm) and 8.7µm bands. No clear core at 8.7µm and no fringes through the N band could be detected for this object with MIDI. A qualitati...
متن کاملDetection of C60 and C70 in a young planetary nebula.
In recent decades, a number of molecules and diverse dust features have been identified by astronomical observations in various environments. Most of the dust that determines the physical and chemical characteristics of the interstellar medium is formed in the outflows of asymptotic giant branch stars and is further processed when these objects become planetary nebulae. We studied the environme...
متن کاملThe Planetary Nebula Luminosity Function
The [O III] λ5007 planetary nebula luminosity function (PNLF) occupies an important place on the extragalactic distance ladder: it is the only standard candle that can be applied to all the large galaxies of the Local Supercluster. We review the method’s precision, and use it to show that the distance scale defined by Cepheids and the Surface Brightness Fluctuation method is likely too large by...
متن کاملPhytoestrogens: recent developments
Phytoestrogens are polyphenolic non-steroidal plant compounds with estrogen like activity exerted through estrogen receptors. These receptors are distributed in several tissues such as male and female reproductive systems, bones, cardiovascular and central nervous systems. These natural phenolic compounds include isoflavonoids, flavonoids, lignans and stilbenes. Isoflavonoids are the most studi...
متن کاملRecent developments in planetary Aeolian studies and their terrestrial analogs
This report summarizes the many advances that have been made in the study of planetary Aeolian processes that have taken place since the first Planetary Dunes Workshop was held in May of 2008, through 2011. Many of the recent studies are facilitated by the wealth and variety of high resolution imaging and spectra data still being returned by multiple spacecraft in orbit and on the surface of Ma...
