A stellar burst reveals the formation mechanism of massive stars

nirs3

November 14th 2016

An outburst from a massive star in formation produced due to the sudden intake of material coming from its accretion disk, has been detected for the very first time.

This discovery is the most solid evidence so far that high mass stars are formed through a similar process to that which gives rise to the low mass ones.

Stars with low mass, like the Sun, are formed from big fragments of clouds of gas and dust, which condense until a central object, or proto star, is formed, growing it up by absorbing gas from a surround disk, and expelling the surplus material through a couple of jets located on both poles. However, it was not known if the most massive stars, with tens of the Sun mass, are formed through the same mechanism. The study of an outburst detected on the massive star in formation NIRS 3, and published today in Nature, has provided the most solid evidence that, in effect, all stars are formed the same.

November 8th 2016

A study shows how are the structure and the temporal variations of the biggest jet stream of the Solar System.

The research, carried out by the Group of Planetary Sciences of the University of País Vasco, has used the PlanetCam camera installed at the Calar Alto Observatory 2.2m Telescope.

The atmosphere of Saturn has the wider and more intense jet stream of all the planets in the Solar System, with winds up to 1.650 km/h, thirteen times the value of the Earth’s hurricane winds, and with an extension of 70.000 km, more than five times our planet’s size. A study lead by University of País Vasco (UPV/EHU) using data from Calar Alto Observatory 2.2m telescope, has just revealed the peculiarities of this jet stream, which nature and energy are still unknown.

October 5th 2016

Calar Alto Observatory participated last September 30th 2016 on the European Night of the Researchers with a stand that showed the Fireball Detection Station that is presently working at the observatory with cameras from both the SMART Project and the Calar Alto External Surveillance system. Some images and videos of the most impressive fireballs were shown during the whole event. The researchers explained the nature and origin of this astronomical phenomena, generating a great expectation in the audience.

New Instrumentation and Legacy Projects for Calar Alto workshop

portada

September 6th 2016

Calar Alto Observatory is an astronomical reference for the Spanish and international communities due to the quality of its telescopes and astronomical instrumentation. With this idea in mind, it is now the time for proposing and selecting the last generation of instruments the community considers the optimum ones to perform front-line scientific projects, unaffordable in other observatories.

This workshop that will be held at the Instituto de Astrofísica de Andalucía (IAA-CSIC) and opened to the Spanish and international scientific communities, is the starting point for this new stage of Calar Alto Observatory and will open the debate to select the best proposals for the new instrumentation and for most challenging Legacy projects.

Please, find here all the information concerning this important workshop.

The researcher, who took office as Calar Alto Observatory Deputy Director since May 2014, has been appointed by CSIC and MPG, the observatory management institutions.

In May 2014, after José María Quintana resignation as Calar Alto Observatory Director, Jesús Aceituno assumed the management of the institution as Deputy Director, in a very difficult and upheaval period for the center, and with a very restrictive budget.

July 8th 2016

This Friday, July 8th, a delegation from the University of Almería (UAL) has visited Calar Alto Observatory installations. Among the collaboration projects that will be launched, stand out the creation of an astronomical lecture room at the UAL, the incorporation of trainees at the Observatory and the creation of a summer course that approach its work to the whole society.

The University of Almería (UAL), Calar Alto Observatory (CAHA) and Instituto de Astrofísica de Andalucía (IAA-CSIC) have ratify a compromise in order to continue with the UAL-CSIC collaboration agreement signed in 1996, progressing in some of its contents. This Friday July 8th, a delegation from UAL, headed by the rector Carmelo Rodriguez, has visited Calar Alto Observatory installations, the biggest observatory in Europe mainland.

The weird system of star CVSO 30: two planets at extreme distances

portadaJuly 6th 2016

A direct image has been taken of a planet so far away from his star that it takes twenty-seven thousand years for completing one orbit, and it shares the system with another planet which completes its orbit in just eleven hours.

Calar Alto Observatory (CAHA, MPG/CSIC) 2.2m Telescope and the Astralux camera has been used on this observation campaign.
