1 Searching For Planets Like Earth around stars like the Sun Derek Buzasi FGCU
2 Roadmap Who am I and how did I get here? Motivation for my research What makes a star like the Sun? How do we find planets? Results so far What next?
3 A Little About Me BA Physics, U. Chicago PhD Astronomy, Penn State Postdoc: HAO/NCAR, Johns Hopkins Visiting Scientist, NASA HQ Visiting Professor, College of Charleston Assistant Professor, Valdosta State Research Scientist, UC Berkeley Associate/Full Professor, US Air Force Academy Affiliate Professor, University of Washington Whitaker Scholar, Florida Gulf Coast University
4 Unconventional Career Path
5 What is Astronomy? The study of physical conditions in (usually faraway parts of) the universe Applies physics, mathematics, computer science, geology, chemistry, etc.
6 Roadmap Who am I and how did I get here? Motivation for my research What makes a star like the Sun? How do we find planets? Results so far What next?
7 Why Astronomy? About 20,000 professional astronomers worldwide Working degree is typically a PhD in Physics/Astrophysics/Astronomy Historically useful for religious purposes, calendars, navigation
8 Why Stars and Exoplanets? We want to know what s out there? The most comprehensible places are those like home We can t understand other planets without understanding other stars
9 Roadmap Who am I and how did I get here? Motivation for my research What makes a star like the Sun? How do we find planets? Results so far What next?
10 What Makes a Star like the Sun? Activity & Cycles Planetary Systems Stellar-Planetary Interactions Activity & Cycles
11 What Makes a Star like the Sun? Mass, radius, temperature, composition, structure Activity level, age, rotation rate, [lack of] companions, presence/absence of planetary system, habitability * How do we measure these parameters? Which parameters are more important? How close to solar is good enough?
12 Parameters of the Sun
13 The Sun as a Star: Context
14 The Sun as a Star: Evolution
15 The Sun as a Star: Structure
16 But The Sun is Variable!
17 Solar Cycles at other Wavelengths
18 Other stars have cycles, too
19 The Solar Wind
20 Visible Manifestations
21 Aurorae on Saturn
22 Tools & Techniques
23 Tools & Techniques
24 Roadmap Who am I and how did I get here? Motivation for my research What makes a star like the Sun? How do we find planets? Results so far What next?
25 How do we find planets? Can we just look for them? Yes, but
26 More Productive Approaches Radial velocity, transits Also gravitational lensing, timing variations, astronometry
27 What methods work best? (so far)
28 Roadmap Who am I and how did I get here? Motivation for my research What makes a star like the Sun? How do we find planets? Results so far What next?
29 Kepler Mission
30 Kepler Mission
31 Orbit & Field
32 Our Solar System
33 The Habitable Zone
34 Solar System Formation (Traditional)
35 Is this what we see elsewhere? Jupiter-like (big & cold) Truly alien! (big and hot) NO! Terrestrial (small and warm)
36
37 Snapshot: Kepler-16 Saturn-sized, 0.7 AU orbit around a binary star!
38 Snapshot: Kepler 11
39 A more promising candidate? HD 40307g: ~ 7.1 M Earth, 0.6 AU
40 In aggregate
41 Lots of terrestrial-mass planets out there! But lots of them are around M dwarfs
42 Planets with Atmospheres But no terrestrial planets yet
43 Giant Planet Migration
44 Not many good candidates yet
45 Quo Vadis? We need to Find solar-like stars Detect potential earth-like planets around them Understand how solar systems form and evolve Search for atmospheres Decide which candidates are the best match
46 Roadmap Who am I and how did I get here? Motivation for my research What makes a star like the Sun? How do we find planets? Results so far What next?
47 Future Missions Kepler-2: ? PLATO: 2024 TESS: 2017 WFIRST: 2024
48 Some open questions How common are planets like the Earth? How do solar systems form? Why is our solar system (apparently) unusual? Does that matter? Does migration affect the presence and habitability of terrestrial planets? Can planets be habitable around active stars? How common are life-sustaining atmospheres around terrestrial planets?
