RVTESS I: Modeling Asteroseismic Signals with Simultaneous Photometry and RVs
Jiaxin Tang, Sharon X. Wang, Yaguang Li +22
Detecting small planets via the radial velocity method remains challenged by signals induced by stellar variability, versus the effects of the planet(s). Here, we explore using Gau…

Use of solid fused silica etalon with broadband metallic coatings for calibration of high-resolution optical spectrograph
Supriyo Ghosh, William Martin, Kajal Kunverji +1
Wavelength calibration is a key factor for high-resolution spectroscopic measurements for precision radial velocities. Hollow-cathode lamps (e.g., ThAr), absorption cells (e.g., io…

Lessons learned from the detection of wide companions by radial velocity and astrometry
Fabo Feng, Guang-Yao Xiao, Hugh R. A. Jones +3
The detection and constraint of the orbits of long-period giant planets is essential for enabling their further study through direct imaging. Recently, it has been highlighted that…
