Improving Binary Millisecond Pulsar Distances with Gaia
Chiara M. F. Mingarelli, Lauren Anderson, Megan Bedell +2
Improved distance measurements to millisecond pulsars can enhance pulsar timing array (PTA) sensitivity to gravitational-waves, improve tests of general relativity with binary puls…
Thorium in solar twins: implications for habitability in rocky planets
Rafael B. Botelho, Andre de C. Milone, Jorge Melendez +10
We have investigated the thorium (Th) abundance in a sample of 53 thin disc solar twins covering a wide range of ages. These data provide constrains on the mantle energy budget of…
Actions are weak stellar age indicators in the Milky Way disk
Angus Beane, Melissa K. Ness, Megan Bedell
The orbital properties of stars in the disk are signatures of their formation, but they are also expected to change over time due to the dynamical evolution of the Galaxy. Stellar…
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…
A TESS Dress Rehearsal: Planetary Candidates and Variables from K2 Campaign 17
Ian J. M. Crossfield, Natalia Guerrero, Trevor David +38
We produce light curves for all ~34,000 targets observed with K2 in Campaign 17 (C17), identifying 34 planet candidates, 184 eclipsing binaries, and 222 other periodic variables. T…
The Chemical Homogeneity of Sun-like Stars in the Solar Neighborhood
Megan Bedell, Jacob L. Bean, Jorge Melendez +9
The compositions of stars are a critical diagnostic tool for many topics in astronomy such as the evolution of our Galaxy, the formation of planets, and the uniqueness of the Sun.…
