Radial velocity precision of ESPRESSO through the analysis of the solar twin HIP 11915
Yuri Netto, Diego Lorenzo-Oliveira, Jorge Meléndez +4
Different stellar phenomena affect radial velocities (RVs), causing variations large enough to make it difficult to identify planet signals from the stellar variability. RV variati…
HD 183579b: A Warm Sub-Neptune Transiting a Solar Twin Detected by TESS
Tianjun Gan, Megan Bedell, Sharon Xuesong Wang +48
We report the discovery and characterization of a transiting warm sub-Neptune planet around the nearby bright ( mag, mag) solar twin HD 183579, delivered by the Tr…
Gemini/Phoenix H-band analysis of the globular cluster AL3
B. Barbuy, H. Ernandes, S. O. Souza +9
The globular cluster AL~3 is old and located in the inner bulge. Three individual stars were observed with the Phoenix spectrograph at the Gemini South telescope. The wavelength re…
Explosive nucleosynthesis of a metal-deficient star as the source of a distinct odd-even effect in the solar twin HIP 11915
Jhon Yana Galarza, Jorge Meléndez, Amanda I. Karakas +2
The abundance patterns observed in the Sun and in metal-poor stars show a clear odd-even effect. An important question is whether the odd-even effect in solar-metallicity stars is…
