ASASSN-21js: A multi-year transit of a ringed disc
T. H. Pramono, M. A. Kenworthy, R. van Boekel
The early-type star ASASSN-21js started to fade in 2021, as was detected by the All Sky Automated Survey for Supernovae, undergoing a multi-year eclipse that is still underway. We…
The SPHERE view of the Orion star-forming region
P. -G. Valegard, C. Ginski, A. Derkink +17
We present SPHERE/IRDIS H-band data for a sample of 23 stars in the Orion Star forming region observed within the DESTINYS (Disk Evolution Study Through Imaging of Nearby Young Sta…
An Episode of Occultation Events in Gaia21bcv
Klaus W. Hodapp, Eric Gaidos, Matthew A. Kenworthy +4
A previously unremarkable star near the Canis Major OB1/R1 association underwent an episode of multiple deep brightness minima. Light curves based on archival Gaia, ZTF, NEOWISE da…
A MUSE view of the asymmetric jet from HD 163296
C. Xie, S. Y. Haffert, J. de Boer +5
Jets and outflows are thought to play important roles in regulating star formation and disk evolution. HD 163296 is a well-studied Herbig Ae star that hosts proto-planet candidates…
Discovery of a directly imaged disk in scattered light around the Sco-Cen member Wray 15-788
A. J. Bohn, M. A. Kenworthy, C. Ginski +10
As part of our on-going survey we have carried out high-contrast imaging with VLT/SPHERE/IRDIS to obtain polarized and total intensity images of the young (Myr old)…
Modeling giant extrasolar ring systems in eclipse and the case of J1407b: sculpting by exomoons?
Matthew A. Kenworthy, Eric E. Mamajek
The light curve of 1SWASP J140747.93-394542.6, a 16 Myr old star in the Sco-Cen OB association, underwent a complex series of deep eclipses that lasted 56 days, centered on A…
Infrared Variability of the Gliese 569B System
Matthew A. Kenworthy, Louis J. Scuderi
Gliese 569B is a multiple brown dwarf system whose exact nature has been the subject of several investigations over the past few years. Interpretation has partially relied on infra…
Piercing the Glare: Direct Imaging Search for Planets in the Sirius System
Christian Thalmann, Tomonori Usuda, Matthew Kenworthy +10
Astrometric monitoring of the Sirius binary system over the past century has yielded several predictions for an unseen third system component, the most recent one suggesting a \leq…
Imaging the Cool Hypergiant NML Cygni's Dusty Circumstellar Envelope with Adaptive Optics
M. T. Schuster, M. Marengo, J. L. Hora +6
We present sub-arcsec angular resolution, high-Strehl ratio mid-IR adaptive optics images of the powerful OH/IR source and cool hypergiant NML Cyg at 8.8, 9.8 and 11.7 um. These im…
