  • Oxygen and chlorine abundances in low-mass planetary nebulae (PNe) (black dots, from Delgado-Inglada et al. 2015) versus the new AGB model predictions for different masses (a few relevant masses are marked) and metallicities. The new models predict that O

    New theoretical models explain the origin of oxygen in low-mass planetary nebulae
    Recently, Delgado-Inglada and collaborators have shown that low-mass (between one and three times the mass of the Sun) planetary nebulae are rich in oxygen, but the standard theoretical models do not predict this. In this work we explain this phenomenon for the first time using theoretical models of nucleosynthesis (production of chemical elements in the interiors of stars) in their precursor AGB stars, which include convective processes, (which transport chemical elements created in the interior to the surface of the star) more efficient than in the standard models. This discovery calls

  • Wide angle view from the Teide Observatory towards the east. Above the horizon you can see the planet Venus, an a little higher up and to the left of Venus is comet Catalina (C/2013 US10). The lights and villages are on Grand Canary. J.C. Casado-staryeart

    Catalina, a Christmas Comet
    Several telescopes at the Teide Observatory (IAC) followed comet Catalina with the aim of characterizing its orbit dynamically. It should be possible to see the central zone of the comet with the naked eye, but to see details you would need binoculars.

    First successful tests of new planet hunter “CARMENES”
    CARMENES, an outstanding novel astronomical instrument, which has been designed to look for Earth-like planets, has successfully passed first “on-sky” tests at the telescope. Scientists and engineers of the Instituto de Astrofísica de Canarias (IAC) have participated in the design and construction of the new “planet hunter”.

    A spectacular Geminids night PHOTONEWS
    Every year at about this date the Earth in its orbit round the Sun meets up with a stream of particles from the asteroid 3200 Phaeton, which produces the meteor shower known as the Geminids. This year we had a good opportunity to observe them. The maximum of this shower, which was expected at 18.00 UT yesterday, December 14 th, occurred with the Moon just emerging from new. For that reason the Instituto de Astrofísica de Canarias (IAC) wanted to present the spectacle to the general public through its website and the sky-live.tv portal. the meteor shower will be broadcast directly from
