¡APOGEE-Sur ha llegado! (APOGEE-South Has Arrived!)

Estamos muy contentos de compartir algunas fotos de la llegada e instalación de APOGEE-Sur en el telescopio du Pont del Observatorio de Las Campanas. Para comenzar, una foto de APOGEE-Sur siendo retirado del contenedor—el mismo contenedor en el que fue colocado el mes pasado en los Observatorios Carnegie.

We are very excited to share with you some photos of the safe arrival and installation of APOGEE-South at the du Pont telescope, Las Campanas Observatory. To start, here is a picture of APOGEE-South being removed from its shipping container — the same container that it was placed in at Carnegie Observatories last month.

Una vez que APOGEE-Sur fue instalado, había que conectar los largos cables de fibra óptica que unen el instrumento con el telescopio. La tarea comenzó con una reunión para discutir la mejor manera de canalizar los cables de fibra óptica.

Once APOGEE-South was in place, its long fiber optic cables had to be fed to the telescope. To begin with, a meeting took place at the APOGEE-South instrument to discuss what needed to be done to ensure that the fiber optics were routed safely.

Después de ultimar los detalles, Fred, Garrett, Nick, Jimmy y Juan desenrollaron los cables de fibra óptica.

After all the details had been ironed out, Fred, Garrett, Nick, Jimmy, and Juan unrolled the fiber train.

Fred, Garrett, Nick, Jimmy, and Juan work in concert to carefully unfurl the 50-meter long fiber train.

Luego, Garrett desde abajo y Mita desde arriba trabajaron con cuidado para conectar la fibra desde el laboratorio criostático a la cúpula.

Then, Garrett from below and Mita from above worked to carefully feed the fiber train from the cryostat lab into the observatory dome.

Derecha: Mita está arriba en la sala de observación, tirando cuidadosamente del cable. También en la foto de la derecha, se aprecia el telescopio (amarillo) y el brazo de soporte (estructura azul oscuro a la izquierda), que será descrito más adelante. Left: Garrett is shown in the cryostat lab feeding the fiber train through a hole in the ceiling. Right: Mita is above the same hole, carefully bringing the fiber train into the observatory room. Also in the right-hand picture, notice the telescope (yellow) and the boom arm (dark blue structure on the left), which will be discussed below.

Also in the right-hand picture, notice the telescope (yellow) and the boom arm (dark blue structure on the left), which will be discussed below.

Abajo en la sala criostática, los manojos de fibras deben ser conectados al criostato donde reside APOGEE-Sur. Como se muestra más abajo, cada manojo de fibras se acopla a un conector.

Down in the cryostat room, the bundles of fibers need to enter the APOGEE-South’s cryostat, or temperature-controlled inner workings. As shown below, this is managed by plugging each fiber bundle into a port.

Manojos de 30 fibras cada uno son conectados al criostato del instrumento APOGEE-Sur. Bundles of thirty fibers each are ported upon entering the APOGEE-South instrument's cryostat.

Bundles of thirty fibers each are ported upon entering the APOGEE-South instrument’s cryostat.

Arriba en la cúpula, el cable que contiene todas las fibras se entrelaza a un largo brazo (la estructura azul en la imagen de abajo) que mantendrá las fibras suspendidas durante el funcionamiento del instrumento.

Up in the observatory dome, the fiber longlink conduit was dressed to a long boom (the blue trusswork in the picture below) that will keep the fibers suspended during operation.

Después de conectar los manojos de fibras al telescopio, John y Nick usan un ordenador para revisar que todas las conexiones se han hecho correctamente. Mientras tanto, Fred, Garrett y Juan unen las fibras al brazo de soporte. After the fiber bundles were all connected to telescope, John and Nick used a computer to check that they had each been placed in the correct port. Meanwhile, Fred, Garrett, and Juan attached the fiber train to the boom.

Al final de la operación las fibras conectaban el criostato, a través del techo y a lo largo del brazo de soporte, con el telescopio. Para celebrar el éxito, el equipo se puso sus camisetas de APOGEE.

When all was said and done, the fibers were safely installed, from cryostat, through the ceiling, along the boom, to the telescope! To celebrate, the crew wore matching APOGEE T-shirts.

¡Camisetas a tono! Buen trabajo en la instalación de las fibras. Matching T-shirts! Job well done on the fiber installation.

A continuación, el sistema óptico debe ser colocado en el criostato. Para hacer ésto, el laboratorio criostático fue transformado en una sala limpia para impedir que el polvo y otras partículas contaminaran el interior del instrumento. Este trabajo se está desarrollando ahora—¡deseemos suerte a nuestro equipo en la siguiente etapa de la instalación del instrumento APOGEE-Sur!

Next, the optics have to be placed in the cryostat. To do this, the cryostat lab is being turned into a clean room to prevent dust and other particulates from polluting the inside of the instrument. This work is ongoing — please wish our crew the best of luck on this next stage of the APOGEE-South instrument installation!

Origin of the Elements in the Solar System

“The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff.” — Carl Sagan

This is an evocative statement. It gets at the heart of the matter. However, it leaves out all the different ways that stars make the elements. It is not just collapsing stars, it is merging stars, burping stars, exploding stars, and the start of the Universe itself.

Below is the latest version of an evolving periodic table color-coded by the origin of the elements in the Solar System. An original version of this was made by Inese Ivans and me in 2008 and refined and improved by Anna Frebel. Versions highlighting different aspects of the physical processes are available on Inese Ivans’ website.

My current version of the periodic table, color-coded by the source of the element in the solar system.

My current version of the periodic table, color-coded by the source of the element in the solar system. Elements with more than one source have the approximate amount due to each process indicated by the amount of area. Tc, Pm, and the elements beyond U do not have long-lived or stable isotopes. I have ignored the elements beyond U in this plot, but not including Tc and Pm looked weird, so I have included them in grey.

For this version, I tried to avoid the technical terms and jargon used in the original plot. I also updated the sources of the heavy elements to reflect the current semi-consensus. This graphic draws on an enormous amount of labor from astronomers and physicists. In an upcoming blog post, I will give details on my sources and assumptions for interested parties. Note that this is for the solar system. There will be additional versions showing what this plot would look like if you were in the early Universe, or if you consider the origin of the elements on the Earth, etc.

However, the main point of this blog post is to present the chart and address the following question:

Why does your version have different information than the well-known Wikipedia entry?

Photos from SDSS at the AAS229

A number of members of the SDSS have been at the American Astronomical Society meeting in Grapevine, Texas this week. Here are some pictures of activities around our exhibit hall booth, from which among other things we gave SDSS plates to a number of teachers and educators. The plates were a big hit and we successfully distribtuted 9 to educational locations in Texas.
