The Little Star That Survived a Supernova

The progenitor of LP40-365 could be a binary star system like the one shown in this animation. Here, an ultra-massive and compact dead star called a white dwarf (shown as a small white star) is accreting matter from its giant companion (the larger red star).

Gemini Confirms a New Class of Variable Stars

Gemini South spectra for three BLAPs. Best fits of stellar atmosphere models are shown with red lines. Effective temperatures, surface gravities, and helium abundances derived for these stars are similar to the values obtained from spectra for the prototype object previously studied. This shows that all the newly discovered variables form a homogeneous class of objects. Credit: Gemini Observatory/AURA/NSF

Semester 2018A Call for Proposals

Gemini Observatory invites its community to propose scientific investigations for the 2018A semester, 1 February 2018 - 31 July 2018.

Instrument Upgrade Projects: Awarded Proposals

2015 IUP Projects

During the 2015 program cycle, Gemini awarded Professor Casey Papovich from Texas A&M University (USA) for the proposal “Two K-filters for F–2 (K2F2).”  Professor Papovich and his team proposed a small upgrade to F-2 by providing two medium band filters, which split the spectral, range 1.9-2.5 microns.  

Gemini IRAF v1.14 Released!

A new version of the Gemini IRAF package (v1.14) has been released.   This release provides support for the new GMOS-N Hamamatsu CCDs.  This release is also the first new release done through the AstroConda distribution.  For Ureka users, a tarball is available for manual installation of the package.

The 2017 Request for Proposals for Instrument Upgrades is now open

The Gemini Observatory consists of two 8-meter telescopes; one located on Maunakea in Hawaii, USA (Gemini North), the other on Cerro Pachón, Chile (Gemini South). The Association of Universities for Research in Astronomy, Inc. (AURA) is the managing organization of the Gemini Observatory under a cooperative agreement with the National Science Foundation (NSF). Gemini Observatory Participant nations are the United States of America, Canada, Brazil, Argentina, and Chile. For more information, visit the Gemini Observatory website at www.gemini.edu.
