Kinematical and dynamical properties of recently discovered bulge and disc star clusters with WINERED
Ilaria Petralia, Dante Minniti, José G. Fernández-Trincado +8
Context. Galactic globular clusters are a very important tool in explaining the characteristics of the Milky Way. Therefore it is essential to determine the kinematical and dynamic…
First Results from WINERED: Detection of Emission Lines from Neutral Iron and a Combined Set of Trace Species on the Dayside of WASP-189 b
Lennart van Sluijs, Emily Rauscher, Eliza M. -R. Kempton +9
Ground and space-based observations have revealed that Ultra Hot Jupiters (UHJs,~) typically have inverted thermal profiles, while cooler hot Jupiters…
Assessing robustness and bias in 1D retrievals of 3D Global Circulation Models at high spectral resolution: a WASP-76 b simulation case study in emission
Lennart van Sluijs, Hayley Beltz, Isaac Malsky +4
High-resolution spectroscopy (HRS) of exoplanet atmospheres has successfully detected many chemical species and is quickly moving toward detailed characterization of the chemical a…
Discovery of WINERED-HVS1: A metal-rich hyper-velocity star candidate ejected from the Galactic center
Kohei Hattori, Daisuke Taniguchi, Takuji Tsujimoto +4
We report the discovery of a metal-rich red giant star, WINERED-HVS1, which is a candidate for a hyper-velocity star (HVS). Its past trajectory suggests that this star may have bee…
First Result for Dark Matter Search by WINERED
Wen Yin, Taiki Bessho, Yuji Ikeda +10
The identity of dark matter has been a mystery in astronomy, cosmology, and particle theory for about a century. Bessho, Ikeda, and Yin (2022), three of the current authors, propos…
MAGIS (Measuring Abundances of red super Giants with Infrared Spectroscopy) project I. Establishment of an abundance analysis procedure for red supergiants and its evaluation with nearby stars
Daisuke Taniguchi, Noriyuki Matsunaga, Naoto Kobayashi +11
[Abbreviated] Context. Given their high luminosities (L>~10^4Lsun), red supergiants (RSGs) are good tracers of the chemical abundances of the young stellar population in the Milky…
