Accurate Photometry of Saturated Stars Using the Point-Spread-Function Wing Technique with Spitzer
Kate Y. L. Su, G. H. Rieke, M. Marengo +1
We report Spitzer 3.6 and 4.5 m photometry of 11 bright stars relative to Sirius, exploiting the unique optical stability of the Spitzer Space Telescope point spread function (P…
Design, Construction, and Test of the Gas Pixel Detectors for the IXPE Mission
L. Baldini, M. Barbanera, R. Bellazzini +91
Due to be launched in late 2021, the Imaging X-Ray Polarimetry Explorer (IXPE) is a NASA Small Explorer mission designed to perform polarization measurements in the 2-8 keV band, c…
On the Use of Field RR Lyrae as Galactic Probes. V. Optical and radial velocity curve templates
V. F. Braga, J. Crestani, M. Fabrizio +29
We collected the largest spectroscopic catalog of RR Lyrae (RRLs) including 20,000 high-, medium- and low-resolution spectra for 10,000 RRLs. We provide the analy…
On the use of field RR Lyrae as Galactic probes: IV. New insights into and around the Oosterhoff dichotomy
M. Fabrizio, V. F. Braga, J. Crestani +30
We discuss the largest and most homogeneous spectroscopic dataset of field RR Lyrae variables (RRLs) available to date. We estimated abundances using both high-resolution and low-r…
X-rays in Cepheids: XMM-Newton Observations of Aql
Nancy Remage Evans, Ignazio Pillitteri, Pierre Kervella +13
X-ray bursts have recently been discovered in the Cepheids Cep and Dor modulated by the pulsation cycle. We have obtained an observation of the Cepheid Aql with the XMM…
Great Observatories: The Past and Future of Panchromatic Astrophysics
L. Armus, S. T. Megeath, L. Corrales +30
NASA's Great Observatories have opened up the electromagnetic spectrum from space, providing sustained access to wavelengths not accessible from the ground. Together, Hubble, Compt…
