Photometry and asteroseismology of delta Scuti stars in Praesepe
We discuss observations and seismic analyses for three multi-periodic delta Scuti stars in the Praesepe cluster: BU, BN and BV Cnc. For two stars (BU and BN Cnc...
Photometry and spectroscopy of the contact binary GSC04778-00152
Photometric and spectroscopic data of the southern contact binary GSC04778-00152 are presented. Six new times of minimum are listed. For modelling purposes, we...
Photometry of asteroid (101955) Bennu with OVIRS on OSIRIS-REx
NASA's OSIRIS-REx spacecraft arrived at its sampling target, asteroid (101955) Bennu, in December 2018 and started a series of global observation campaigns...
Photometry of high-redshift blended galaxies using deep learning
The new generation of deep photometric surveys requires unprecedentedly precise shape and photometry measurements of billions of galaxies to achieve their main...
Photometry of Outer Solar System Objects from the Dark Energy Survey. I. Photometric Methods, Light-curve Distributions, and Trans-Neptunian Binaries
We report the methods of and initial scientific inferences from the extraction of precision photometric information for the >800 trans-Neptunian objects (TNOs)...
Photometry of Outer Solar System Objects from the Dark Energy Survey. II. A Joint Analysis of Trans-Neptunian Absolute Magnitudes, Colors, Light Curves and Dynamics
For the 696 trans-Neptunian objects (TNOs) with absolute magnitudes 5.5 < H r < 8.2 detected in the Dark Energy Survey, we characterize the relationships...
Photometry of SN 2002bo with template image subtraction
VRI photometry of the type Ia supernova 2002bo is presented. This SN exploded in a dusty region of the host galaxy NGC 3190, thus, subtraction of a template...
The authors present the results of a statistical analysis of the penumbra of sunspots. The intensity distribution, and several parameters derived from it, is...
