Planet place
This collection of short stories explores the effect of place on the lives of various characters striving to define themselves within their geographical, social, and biological realities. The stories' central characters are predominantly young; the environments they encounter are impersonal, …

Minor planet astrophotometry
Historically, the Minor Planet Center (MPC) has concentrated on improving the quality of the astrometric observations and the resulting orbits of minor planets. In light of long-standing complaints in the literature about the quality of the photometric parameters for the minor planets, there has …

Friday is a Planet: Stories
Friday is a Planet: Stories is a collection of short fiction that explores the ways loss can alter family bonds. Characters in these stories have lost daughters, sisters, mothers, and friends. Some characters go to extreme lengths to return to their loved ones—one woman hallucinates, another time …

Fear of a Blank Planet
This study is organized into four major chapters. In the first chapter, the various grounds traversed by affect and the problems of writing 'about' affect are established. The second chapter reads across Continental philosophy to extract and expand upon the undertheorized spatio-temporalities of …

Understand thy star, understand thy planet
… impediment to the discovery of Earth-like planets. Indeed, future space missions and next generation spectrographs are technically capable at finding and characterising Earth-analogue planets. However, it is now stellar activity that poses a critical challenge on the pathway to detect …

Dynamical instabilities in disc-planet interactions
Protoplanetary discs can be dynamically unstable due to structure induced by an embedded giant planet. In this thesis, I discuss the stability of such systems and explore the consequence of instability on planetary migration. I present semi-analytical models to understand the formation of the …

Disc-planet interactions in inviscid discs
Planets are born in protoplanetary discs (PPDs), made of gas and dust, which surround newly formed stars. Gravitational coupling provides planets with means to interact with their birth environment, leading to the excitation of global spiral density waves, which drive evolution of the disc (such as …

Finding the location of Planet Nine
To find Planet Nine, we use N-body simulations to find the true anomaly of Planet Nine that would render distant KBOs the most stable. We obtain an interval of 162-198°matching the intervals given by Medvedev & Vavilov (2016) of 176-184° and Brown & Batygin (2016) of 180°. According to our results, …

Content Management in Planet-Scale Video CDNs
Global video Content Distribution Networks (CDNs) serve a significant fraction of the entire Internet traffic through a global network of cache servers. Effective handling of the massive traffic at the edge is vital for the feasibility of these CDNs, which can otherwise incur significant monetary …

Planet formation and evolution in protoplanetary disc
In the last decades, thousands of exoplanets have been detected, revealing a variety of characteristics different from those of the Solar System's planets - the only planets orbiting a main sequence star known until 1995. This enhanced the interest in processes of planet formation and evolution …

Planet formation, resonant drag instabilities, and vortices
… of this thesis is a brief overview of modern planet formation theory. I first present the four critical observations that any model should reproduce: planets form from the aggregation of countless dust grains early in the life of almost every protoplanetary disc . I then describe the main …

Bio-energy system analysis: Profit, planet, and policy
Climate change has escalated in the last decade, affecting every region globally, making it one of today's most important issues. As a response to climate change, the scientific community and politicians have been advocating the shift from a fossil-based economy to a bio-based economy as one of my …

Extrasolar planet transit photometry at Wallace Astrophysical Observatory
Extrasolar planet transit photometry is a relatively new astronomical technique developed over the past decade. Transit photometry is the measurement of a star's brightness as an orbiting planet passes in front of the star as seen from the Earth. Recently, members of MIT's Planetary Astronomy Lab …

Time series photometry of the dwarf planet Eris
This project utilizes time series photometry to attempt to find the period of the newly discovered Kuiper Belt Object (KBO), Eris. Eris is known to have a radius slightly larger than Pluto and an extremely high albedo of 86%, indicative of fresh surface ices. This high albedo makes it likely that …
