Millimagnitude Photometry for Transiting Extrasolar Planetary Candidates IV: The Puzzle of the Extremely Red OGLE-TR-82 Primary Solved
Sergio Hoyer, Sebastian Ramirez Alegria, Valentin D. Ivanov +12
We present precise new V, I, and K-band photometry for the planetary transit candidate star OGLE-TR-82. Good seeing V-band images acquired with VIMOS instrument at ESO VLT allowed…
VSOP: The Variable Star One-shot Project I. Project presentation and first data release
T. H. Dall, C. Foellmi, J. Pritchard +21
The Variable Star One-shot Project (VSOP) is aimed at (1) providing the variability type and spectral type of all unstudied variable stars, (2) process, publish, and make the data…
The Variable Star One-shot Project, and its little child: Wikimbad
C. Foellmi, T. H. Dall, J. Pritchard +21
The Variable Star One-shot Project (VSOP) aimed at providing to the world-wide stellar community the necessary one-shot spectrum of unstudied variable stars, too often classified a…
Carbon Stars and C/M Ratio in the WLM Dwarf Irregular Galaxy
A. T. Valcheva, V. D. Ivanov, E. P. Ovcharov +1
We identify the rich Carbon star population of the Magellanic-type dwarf irregular galaxy WLM (Wolf-Lundmark-Melotte) and study its photometric properties from deep near-IR observa…
Millimagnitude Photometry for Transiting Extrasolar Planetary Candidates: II. Transits of OGLE-TR-113-b in the Optical and Near-IR
Rodrigo F. Díaz, Sebastián Ramírez, José Miguel Fernández +10
We present precise V and Ks-band transit photometry for the planetary host star OGLE-TR-113. Using the Ks-band photometry, we confirm the dwarf nature of OGLE-TR-113, and obtain ne…
