MagAO-Classic posts

Well, we at least made it to Dallas. We’ve been talking to other people here also trying to get to Santiago. Apparently flights have been routinely canceled over the last few days due to volcanic ash. I thought we were far enough north that it isn’t a issue, but guess not. ...

Nowhere fast — that’s how you might describe the MagAO run so far. This post should have been “Day 0” (our traditional day before Laird arrives at LCO), but as you can see we’re moving backwards. Laird, Katie and Jared tried to leave Tucson today, but, well, they just decided to close the ...

The MagAO team is in the final stages of preparations for 2015A — Laird, Katie, and Jared depart for Chile this coming Saturday. We’re going down early to do some work on Clio and replace a motor. By the time we come home, nearly 7 weeks will have passed. Our preparations have included laying in a ...

We have just finished designing, and are fabricating, new vector apodizing phase plate (APP) coronagraphs for Clio2. We plan to install these during the last week of April, 2015, prior to the 2015A run. We will be commissioning and characterizing them at the beginning of the run. They will be available for observations ...

Abstract: NaSt1 is a peculiar emission-line star embedded in an extended nebula of optical emission with a compact dusty core. This object has been characterized as a Wolf-Rayet (WR) star cloaked in an opaque nebula of material that shows signs of advanced nuclear processing in the core of a massive star. To discern ...

Now that the MagAO team has (mostly) recovered from our epic 6 week stay at LCO, we are turning our attention to processing all of the great data we’ve been taking. We’re also happy to announce two new publications based on MagAO data which have been accepted to the Astrophysical Journal, both of which ...

Abstract: We present multi-epoch non-redundant masking observations of the T Cha transition disk, taken at the VLT and Magellan in H, Ks, and L’ bands. T Cha is one of a small number of transition disks that host companion candidates discovered by high-resolution imaging techniques, with a putative companion at a position angle of 78 ...

Abstract: We used the Magellan adaptive optics (MagAO) system and its VisAO CCD camera to image the young low mass brown dwarf companion CT Chamaeleontis B for the first time at visible wavelengths. We detect it at r’, i’, z’, and Ys. With our new photometry and Teff~2500 K derived from the shape of its K-band ...

Abstract: We present resolved images of the HR 4796A debris disk using the Magellan adaptive optics system paired with Clio-2 and VisAO. We detect the disk at 0.77 microns, 0.91 microns, 0.99 microns, 2.15 microns, 3.1 microns, 3.3 microns, and 3.8 microns. We find that the deprojected center of the ring is offset from the star ...

We utilized MagAO to obtain very high-resolution visible light images of HD142527 with MagAO’s VisAO science camera. In the median seeing conditions of the 6.5m Magellan telescope (0.5 − 0.7′′), we find MagAO delivers 24-19% Strehl at Ha (0.656 mm). We detect a faint companion (HD142527B) embedded in this young transitional disk system at just ...
