Keck, Gemini, and Palomar 200-inch visible photometry of red and very-red Neptunian Trojans
B. T. Bolin, C. Fremling, A. Morbidelli +9
Neptunian Trojans (NTs), trans-Neptunian objects in 1:1 mean-motion resonance with Neptune, are generally thought to have been captured from the original trans-Neptunian protoplane…
Ca II Triplet Spectroscopy of Small Magellanic Cloud Red Giants. VI. Analysis of chemical properties of the Main Body
B. J. De Bortoli, M. C. Parisi, L. P. Bassino +5
We derived radial velocities and CaT metallicity of more than 150 red giants stars in six SMC star clusters and their surrounding fields, with the instrument GMOS on GEMINI-S. The…
Size and Shape Constraints of (486958) Arrokoth from Stellar Occultations
Marc W. Buie, Simon B. Porter, Peter Tamblyn +130
We present the results from four stellar occultations by (486958) Arrokoth, the flyby target of the New Horizons extended mission. Three of the four efforts led to positive detecti…
Circumnuclear rings and Lindblad resonances in spiral galaxies
E. O. Schmidt, D. Mast, R. Diaz +5
In order to study the location of circumnuclear rings (CNR) and their possible relation with the inner Lindblad resonances (ILR), we investigate a sample of spiral galaxies. For th…
RAMSES II - RAMan Search for Extragalactic Symbiotic Stars. Project concept, commissioning, and early results from the science verification phase
R. Angeloni, D. R. Gonçalves, S. Akras +16
Symbiotic stars (SySts) are long-period interacting binaries composed of a hot compact star, an evolved giant star, and a tangled network of gas and dust nebulae. They represent un…
Towards an improvement in the spectral description of central stars of planetary nebulae
W. Weidmann, R. Gamen, D. Mast +7
Context. There are more than 3000 known Galactic planetary nebulae (PNe), but only 492 central stars of Galactic planetary nebulae (CSPN) have known spectral types. It is vital to…
First performance of the gems + gmos system. Part1. Imaging
Pascale Hibon, Vincent Garrel, Benoit Neichel +6
During the commissioning of the Gemini MCAO System (GeMS), we had the opportunity to obtain data with the Gemini Multi-Object Spectrograph (GMOS), the most utilised instrument at G…
Limits on Quaoar's Atmosphere
Wesley C Fraser, Chad Trujillo, Andrew W. Stephens +4
Here we present high cadence photometry taken by the Acquisition Camera on Gemini South, of a close passage by the km radius Kuiper Belt Object, (50000) Quaoar, of a r'=2…
GNOMOS: The Gemini NIR-Optical Multi Object Spectrograph
Ricardo P. Schiavon, Andy Adamson, Kristin Chiboucas +20
This paper is a response to a call for white papers solicited by Gemini Observatory and its Science and Technology Advisory Committee, to help define the science case and requireme…
