SPHERE/SHINE reveals concentric rings in the debris disk of HIP 73145
M. Feldt, J. Olofsson, A. Boccaletti +22
The debris disk of HIP73145 has been detected in scattered light in the near-IR, and at far-IR wavelengths before, but no substructure has been seen so far. Detection of such subst…
First scattered-light images of the gas-rich debris disk around 49 Ceti
É. Choquet, J. Milli, Z. Wahhaj +31
We present the first scattered-light images of the debris disk around 49 ceti, a ~40 Myr A1 main sequence star at 59 pc, famous for hosting two massive dust belts as well as large…
X-Shooter spectroscopy of young stellar objects in Lupus: Accretion properties of class II and transitional objects

We present the results of a study of the stellar and accretion properties of the (almost) complete sample of class II and transitional YSOs in the Lupus I, II, III and IV clouds, b…
In and out star formation in z~1.5 quiescent galaxies from rest-frame UV spectroscopy and the far-infrared
Raphael Gobat, Emanuele Daddi, Veronica Strazzullo +18
We present a sample of 34 spectroscopically confirmed BzK-selected ~1e11 Msun quiescent galaxies (pBzK) in the COSMOS field. The targets were initially observed with VIMOS on the V…
A Comparative Study of Multiwavelength Theoretical and Observed Light Curves of Cepheid Variables
Anupam Bhardwaj, Shashi M. Kanbur, Marcella Marconi +3
We analyse the theoretical light curves of Cepheid variables at optical ({\it UBVRI}) and near-infrared ({\it JKL}) wavelengths using the Fourier decomposition and principal compon…
Interferometric Evidence for Quantum Heated Particles in the Inner Region of Protoplanetary Disks around Herbig Stars
L. Klarmann, M. Benisty, M. Min +6
To understand the chemical composition of planets, it is important to know the chemical composition of the region where they form in protoplanetary disks. Due to its fundamental ro…
The Chandra Deep Field-South Survey: 7 Ms Source Catalogs
B. Luo, W. N. Brandt, Y. Q. Xue +23
We present X-ray source catalogs for the Ms exposure of the Chandra Deep Field-South (CDF-S), which covers a total area of 484.2 arcmin. Utilizing WAVDETECT for init…
A Type II Supernova Hubble diagram from the CSP-I, SDSS-II, and SNLS surveys
T. de Jaeger, S. González-Gaitán, M. Hamuy +15
The coming era of large photometric wide-field surveys will increase the detection rate of supernovae by orders of magnitude. Such numbers will restrict spectroscopic follow-up in…
