First results of a continuous monitoring campaign of the PLATO Southern field

Thomas Granzer, Jorg Weingrill, Klaus G. Strassmeier +1

The BMK10k project started as an ancillary project to the PLATO ESA mission, dedicated to photometrically monitor the PLATO Southern field, to help with source confusion, and to mi…

Large-scale time-series spectroscopy for stellar ages

David Gruner, Sydney A. Barnes, Ansgar Reiners +16

To date, Galactic Astronomy has largely concerned itself with astrophysical processes, and with the locations, space motions and compositions of objects. Consider, for example, the…

ANDES, the high-resolution spectrograph for the ELT: RIZ Spectrograph preliminary design

Bruno Chazelas, Yevgeniy Ivanisenko, Audrey Lanotte +44

We present here the preliminary design of the RIZ module, one of the visible spectrographs of the ANDES instrument 1. It is a fiber-fed high-resolution, high-stability spectrograph…

New insights into the rotational evolution of near-solar age stars from the open cluster M67

D. Gruner, S. A. Barnes, J. Weingrill

Gyrochronology allows the derivation of ages for cool main sequence stars from their observed rotation periods and masses, or a suitable proxy of the latter. It is increasingly wel…

A rotational age for the open cluster NGC 2281

D. J. Fritzewski, S. A. Barnes, J. Weingrill +3

Cool star rotation periods have become an important tool in determining ages of open clusters. We aim to estimate the age of the open cluster NGC 2281 based on the rotational prope…

The Rotation Period Distribution in the Young Open Cluster NGC 6709

E. M. Cole-Kodikara, S. A. Barnes, J. Weingrill +1

Open clusters serve as a useful tool for calibrating models of the relationship between mass, rotation, and age for stars with an outer convection zone due to the homogeneity of th…

A color-period diagram for the open cluster M 48 (NGC 2548), and its rotational age

Sydney A. Barnes, Jörg Weingrill, Thomas Granzer +2

Rotation periods are increasingly being used to derive ages for cool single field stars. Such ages are based on an empirical understanding of how cool stars spin down, acquired by…

Broad-band spectrophotometry of the hot Jupiter HAT-P-12b from the near-UV to the near-IR

M. Mallonn, V. Nascimbeni, J. Weingrill +13

The detection of trends or gradients in the transmission spectrum of extrasolar planets is possible with observations at very low spectral resolution. Transit measurements of suffi…

Transmission spectroscopy of the inflated exo-Saturn HAT-P-19b

M. Mallonn, C . von Essen, J. Weingrill +7

We observed the Saturn-mass and Jupiter-sized exoplanet HAT-P-19b to refine its transit parameters and ephemeris as well as to shed first light on its transmission spectrum. We mon…

Extrasolar Planets Orbiting Active Stars

Jörg Weingrill

New discoveries of transiting extrasolar planets are reported weekly. Ground based surveys as well as space borne observatories like CoRoT and Kepler are responsible for filling th…

The SARS algorithm: detrending CoRoT light curves with Sysrem using simultaneous external parameters

Aviv Ofir, Roi Alonso, Aldo Stefano Bonomo +31

Surveys for exoplanetary transits are usually limited not by photon noise but rather by the amount of red noise in their data. In particular, although the CoRoT spacebased survey d…

Planetary transit candidates in COROT-IRa01 field

S. Carpano, J. Cabrera, R. Alonso +35

Context: CoRoT is a pioneering space mission devoted to the analysis of stellar variability and the photometric detection of extrasolar planets. Aims: We present the list of planet…

TT Arietis - Observations of a Cataclysmic Variable Star with the MOST Space Telescope

J. Weingrill, G. Kleinschuster, R. Kuschnig +5

We measured the photometric flux of the cataclysmic variable TT Arietis (BD+14 341) using the MOST space telescope. Periodic oscillations of the flux reveal the orbital period as w…
