Ingrid Stairs

Ingrid Stairs is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Ingrid Stairs rather than just read about it. In short: Ingrid Stairs is a Canadian astronomer at the University of British Columbia. She studies pulsars and their companions as a way to study binary pulsar evolution, pulsar instrumentation and polarimetry, and Fast Radio Bursts (FRBs).

Key takeaways

Ingrid Stairs belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Ingrid Stairs to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Ingrid Stairs from memory before moving on to harder problems.

Reference excerpt

Ingrid Stairs is a Canadian astronomer at the University of British Columbia. She studies pulsars and their companions as a way to study binary pulsar evolution, pulsar instrumentation and polarimetry, and Fast Radio Bursts (FRBs). She was awarded the 2017 Rutherford Memorial Medal for physics of the Royal Society of Canada, and was elected as a Fellow of the American Physical Society in 2018.

Education Stairs earned her undergraduate Honors degree from McGill University in 1993, and her Masters and PhD degrees from Princeton University in 1995 and 1998, respectively. For her PhD research, she worked with Professor Joe Taylor.

Career From 1998 to 2000, Stairs was a postdoctoral fellow at the Jodrell Bank Observatory in the United Kingdom. From 2000 to 2002, she was a research associate at NRAO in Green Bank, West Virginia. She became an assistant professor at the University of British Columbia in 2002, an associate professor in 2007, and a full professor in 2012.

Research Stairs investigates various topics related to the science of extreme gravitational objects. She uses large scale pulsar searches with both the Arecibo Telescope and Green Bank Telescope to study pulsar populations and their evolution and to find new millisecond pulsars and exotic binary systems. She has collaborated in the assembly of coherent dedispersion instruments for Arecibo and Green Bank. She times the bursts from millisecond pulsars as a member of the NANOGrav experiment. In addition to finding pulsars, she uses long term pulsar timing to study the orbital dynamics of pulsar systems, such as and interaction between the two stars in the system. She has extensively studied relativistic binary systems like B1534+12, J1906+0746, and the double pulsar J0737-3039A/B. She also tracks some young pulsars, such as J1740-3502, which has a massive binary companion, and PSR 1828-11, which undergoes correlated timing and magnetospheric changes. Stairs is part of the CHIME FRB and pulsar collaborations. CHIME is currently operational and has released many new FRB candidates, including new repeating FRB candidates. Stairs was responsible for managing the installation of the CHIME pulsar instrument.

Worked examples

Example 1 — a first encounter with Ingrid Stairs

Start with the simplest possible case. Write down what Ingrid Stairs claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Ingrid Stairs before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Ingrid Stairs ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Ingrid Stairs

In research: Ingrid Stairs appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Ingrid Stairs in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Ingrid Stairs is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century Canadian astronomers, Canadian women astronomers, Fellows of the American Physical Society, so understanding it makes those chapters shorter.
In everyday life: Look for Ingrid Stairs outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
