The Solar Twin Planet Search: The age - chromospheric activity relation
Diego Lorenzo-Oliveira, Fabrício C. Freitas, Jorge Meléndez +8
It is well known that the magnetic activity of solar type stars decreases with age, but it is widely debated in the literature whether there is a smooth decline or if there is an e…
Kepler-11 is a Solar Twin: Revising the Masses and Radii of Benchmark Planets Via Precise Stellar Characterization
Megan Bedell, Jacob L. Bean, Jorge Melendez +7
The six planets of the Kepler-11 system are the archetypal example of a population of surprisingly low-density transiting planets revealed by the Kepler mission. We have determined…
18 Sco: a solar twin rich in refractory and neutron-capture elements. Implications for chemical tagging
J. Melendez, I. Ramirez, A. I. Karakas +12
We study with unprecedented detail the chemical composition and stellar parameters of the solar twin 18 Sco in a strictly differential sense relative to the Sun. Our study is mainl…
High Precision Abundances of the Old Solar Twin HIP 102152: Insights on Li Depletion from the Oldest Sun
TalaWanda R. Monroe, Jorge Meléndez, Iván Ramírez +13
We present the first detailed chemical abundance analysis of the old 8.2 Gyr solar twin, HIP 102152. We derive differential abundances of 21 elements relative to the Sun with preci…
