Searching for new solar twins: The Inti survey for the Northern Sky
J. Y. Galarza, R. López-Valdivia, D. Lorenzo-Oliveira +9
Solar twins are key in different areas of astrophysics, however only just over a hundred were identified and well-studied in the last two decades. In this work, we take advantage o…
The ancient main-sequence solar proxy HIP 102152 unveils the activity and rotational fate of our Sun
Diego Lorenzo-Oliveira, Jorge Meléndez, Geisa Ponte +1
We present a detailed analysis of the possible future Sun's rotational evolution scenario based on the 8 Gyr-old solar twin HIP 102152. Using HARPS high-cadence observations (and T…
The effect of stellar activity on the spectroscopic stellar parameters of the young solar twin HIP 36515
Jhon Yana Galarza, Jorge Meléndez, Diego Lorenzo-Oliveira +7
Spectroscopic equilibrium allows us to obtain precise stellar parameters in Sun-like stars. It relies on the assumption of the iron excitation and ionization equilibrium. However,…
Constraining the evolution of stellar rotation using solar twins
Diego Lorenzo-Oliveira, Jorge Meléndez, Jhon Yana Galarza +7
The stellar Rotation Age relation is commonly considered as a useful tool to derive reliable ages for Sun-like stars. However, in the light of \kepler\ data, the presence of…
